Answer:
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
