Step by step solution

01

Step 1. Given Information.

Consider the given information.

First-term is 11 and the common difference isd=-8.

02

Step 2. Find the first five terms.

Use the first term and add the common difference. Then add the common difference to that result to get the next term, and so on.

a1=11

And,

a2=11-8=3

And,

a3=3-8=-5

And,

role="math" localid="1645271203725" a4=-5-8=-13

And,

a5=-13-8=-21
