Identify the correct function for the following sequence.

15, 22, 29, 36, ...

Step-by-step explanation:

22-15=7

f (x) = 15+7 (x-1) = 8+7x

f (x) = 7x + 8

Step-by-step explanation:

Explanation:

In order to find the equation you need to find the y-intercept of the sequence first. Since the first number is 15, the function should be a y-intercept of 8. This is because 15 is considered the second term in this situation. There is a common difference of 7, which means every x gains 7 for y. Here is the equation below.

Equation:

f (x) = 7x + 8
