What are the values of r and a1 for

The first term a is 3

The common difference is 1/5

Step-by-step explanation:

Here, we want to get the value for the common difference and the first term

The common difference is simply what we have in the bracket

This is 1/5

The initial term can be obtained by substituting the value of 1 for k

Mathematically, we have this as

3(1/5)^(1-1)

= 3(1/5)^0

= 3 * 1 = 3

-4
