Answer:

an = 15 (1/5)^(n-1)

Explanation:

In a geometric series, each term is multiplied by a common ratio to get the next term. Such that:

an = a₁ (r)^(n-1)

Here, the first term, a₁, is 15. The common ratio, r, is 1/5, because each term is divided by 5 to get the next term. So:

an = 15 (1/5)^(n-1)

Your answer is correct, well done!
