Given:

The arithmetic sequence is −15, −33, −51, −69.

To find:

The nth term of the arithmetic sequence.

Solution:

We have,

−15, −33, −51, −69

Here,

First term: a = -15

Common difference is

Now, nth term  of an arithmetic sequence is

Substitute a=-15 and d=-18.

Therefore, the nth term of the given arithmetic sequence is .
