Write an equation for the nth term of the arithmetic sequence. Then graph the first five terms in the Sequence.
-3,-8,-13,-18

I got 5n-8 as my formula.

Then plugged 5 in for n and got 17 for the 5th number in the sequence.

Is this correct?

Does your formula work with what was given?

Answered by ABCV
The general formula of an arithmetic sequence is
An = A1 + (n-1)d
where An refers to the nth term,
A1 refers to the first term
d refers to the common difference

Try using the above formula
