Question

Select the correct answer.

Select the function that defines the given sequence.

-11, -8, -5, -2, 1, . . .

Answer 1

• f(x) = 3x - 14

Explanation:

Given sequence:

• -11, -8, -5, -2, 1, . . .

This is an AP with first term of - 11 and common difference of 3

As an AP it is linear function with points

• (1, -11), (2, -8), ...

We can define slope as m = 3 and y-intercept as (0, -14) so the function is:

• f(x) = 3x - 14
