Find an equation for the nth term of the arithmetic sequence.
-17, -12, -7, -2,
a. an = -17 + 5(n + 2)
b. an = -17 + 5(n + 1)
c. an = -17 + 5(n - 1)
d. an = -17 x 5(n - 1)

Option C

Step-by-step explanation:

we know that

In an Arithmetic Sequence the difference between one term and the next is a constant, and this constant is called the common difference

The formula of the nth term of the arithmetic sequence is

where

is the nth term

is the first term

d is the common difference

n is the number of terms

In this problem we have

Find the common difference d

The common difference is d=5

substitute the values in the formula
