The given statement is of Inductive Reasoning as "the next number you get should be 20" is just a generalization, there is nothing conclusive.
In the Inductive reasoning , if the statements are true then it does not mean that the conclusion will also be true.
In the Deductive reasoning , if the statements are true then the conclusion need to be true.
In the given question ,
We are playing a lottery and buy tickets with randomly generated numbers.
As the numbers are randomly generated we cannot conclude anything concrete/logically about the next number.
It is random that we have found the pattern and found the next number to be 20.
It is just a mere coincidence that the next number is 20 .
There is nothing Logical for the next number to be 20 as the numbers are randomly generated.
Since in this situation we have made a generalization after observing the pattern , "the next number you get should be 20" is mere generalization and thus, it represents Inductive Reasoning .
Therefore , this case is the case of Inductive Reasoning , the correct option is (a) Inductive.
The given question is incomplete , the complete question is
you're playing the lottery, and you buy a ticket with randomly generated numbers. the first three numbers you get are 5, 10, and 15. thus, the next number you get should be 20.

The sum of two consecutive numbers is 85, find the numbers
Answer:
85
Step-by-step explanation:
Consecutive numbers are numbers that follow each other in order. The two consecutive numbers are 42 and 43.
42+43=85
Answer:
42 & 43
Step-by-step explanation:
Let the two consecutive numbers be x and x+1 .
Here it is given that the sum of two consecutive numbers is 85.
So we get the equation,
x + (x+1) = 85
We get,
x + x + 1 = 85
2x + 1 = 85
Transposing +1 to RHS,
2x = 85 - 1
2x = 84
Transposing 2 to RHS,
x = 84 ÷ 2
Therefore, we get x = 42
Therefore, the two numbers are x and x+1, so they are: 42 and 43.

find four rational between -5/6 and -4/9
The four rational number between -5/6 and -4/9 are (-43/54, -37/54, -35/54 and -31/54).
First we will make the denominator of -5/6 and -4/9 same by multiplying the numerator and denominator of -5/6 by 9 and multiply the numerator and denominator of -4/9 by 6, we get
-5x9/6x9 = -45/54 and -4x6/9x6 = -24/54
Now, we have -45/54 and -24/54 whose denominator are same.
we can choose or pick any four integers as numerator in between -45 and -24 with denominator as 54.
-43/54, -37/54, -35/54 and -31/54 are the four rational number having numerator in between -45 and -24 with denominator as 54.
Therefore, -43/54, -37/54, -35/54 and -31/54 are the four rational number between -5/6 and -4/9.

How to find the inverse function
f ⁻¹( x)= x^2+4 is the inverse of f(x)= [tex]\sqrt{x-4}[/tex]
what is an inverse function ?
An inverse function or an anti function is defined as a function, which can reverse into another function. In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by 'f' or 'F', then the inverse function is denoted by f-1 or F-1.
write f(x)= [tex]\sqrt{x-4}[/tex] as an equation
y= [tex]\sqrt{x-4}[/tex]
interchange the variables
x= [tex]\sqrt{y-4}[/tex]
solve the equation for y we get
squaring both side ,we have
x^2 = y-4
this implies that
y= x^2 +4
replace y with f ⁻¹( x) to show the final answer
f ⁻¹( x)= x^2+4
Hence, f ⁻¹( x)= x^2+4 is the inverse of f(x)= [tex]\sqrt{x-4}[/tex]

Sam will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $65 and costs an additional $0.30 per mile driven. The
second plan has no initial fee but costs $0.80 per mile driven. How many miles would Sam need to drive for the two plans to cost the same?
Sam would need to drive for the two plans to cost the same is 130 miles.
Let, x = Number of miles driven
y = Total cost
The first plan:
Initial fee = $65
Cost of 1 mile = $0.3
Cost of drive x mile = $0.3x
In total, you will pay
y = 0.3x + 65 for the first plan.
The second plan:
There are no initial costs, but
Cost of 1 mile = $0.80
y = 0.80x
Now we have two equations
y = 0.3x + 65
y = 0.80x
As we know that y is equal to both 0.3x + 65 and 0.80x, this means we can equate the right hand sides and solve for x.
0.3x + 65 = 0.80x
0.80x - 0.3x = 65
0.5x = 65
x = 65÷0.5
x = 130
The cost of two plans will be same when Sam drive 130 miles.

By measuring the amount of carbon-14 in an object, a palaeontologist can determine its approximate age. The amount of carbon- 14 in an object is given by y=a e⁻⁰.⁰⁰⁰¹²t, where a is the amount of carbon- 14 originally in the object, and t is the age of the object in years. In 2003, a bone believed to be from a dire wolf was found at the La Brea Tar Pits. The bone contains 14 % of its original carbon-14. How old is the bone?
b. What properties of logarithms and exponents can you use to solve the equation?
The bone is approximately 16384 years old, as solved by basic algebra and logarithm.
The properties of logarithms and exponents so used are: [tex]log_b(a)^m=m(log_b(a))[/tex], [tex]log_e(e) = 1[/tex]
What is basic algebra and logarithm?Numbers, variables, constants, expressions, equations, linear equations, and quadratic equations are all part of the basics of algebra. Additionally, the algebraic expressions contain the basic arithmetic operations of addition, subtraction, multiplication, and division.This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.Let 'a' be the original amount of the object.
Then, according to question, for y = amount of carbon in the object, y = 0.14(a) (as the bone contains 14% of its original carbon-14).
We are also given that: y = a [tex]e^{-0.00012t}[/tex]
On substituting the value of y, we get: 0.14a = a [tex]e^{-0.00012t}[/tex]
By basic algebra, we can solve it as:
=> 0.14 = [tex]e^{-0.00012t}[/tex]
=> ln (0.14) = ln ([tex]e^{-0.00012t}[/tex]) (taking natural logarithm on both sides)
=> ln (0.14) = - 0.00012t (as [tex]log_b(a)^m=m(log_b(a))[/tex]; further [tex]log_e(e) = 1[/tex])
=> [tex]\frac{ln(0.14)}{-0.00012}[/tex] = t
=> t = 16384 years (approx.)
Hence, the bone is approximately 16384 years old, as solved by basic algebra and logarithm; The properties of logarithms and exponents so used are: [tex]log_b(a)^m=m(log_b(a))[/tex], [tex]log_e(e) = 1[/tex].

The fundamental logarithmic function has the notation f(x) = log(r) y = log(x), where a > 0. The exponential function ay = x's inverse is represented by this. The common logarithm (log) or natural logarithm (ln) are examples of log functions (log).
The exponential function of the type aˣ = N can be converted into the logarithmic function logₐN = x. A Napier logarithm table can be used to determine the logarithmic value of any number. Logarithms are often calculated using a base of 10, therefore it is possible to get the logarithmic value of any number.
we have the exponential form as aˣ = N
