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?
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
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
