A geometric sequence is defined recursively by an = 15an-1. The first term of the sequence is 0.0001. Which of the following is the explicit formula for the nth term of the sequence?

an = 15an-1.

So r =15 ; First term, a = .0001

Explicit formula =ar^(n-1)

= .0001 (15)^(n-1)

Please let me know if you have any questions and best me if you are satisfactory.
