Find an equation for the nth term of the arithmetic sequence.

-17, -12, -7, -2, ...

an = -17 + 5(n + 2)
an = -17 + 5(n + 1)
an = -17 + 5(n - 1)
an = -17 x 5(n - 1)

Answer 1

-17 + 5(n - 1)

Explanation:

The general form is a1 + d(n - 1) where a1 = first term and d = common difference

So its -17 + 5(n - 1)
