Use the ratio test to find whether the series diverges or converges.

1/5^n (1 to infinity)

I think the limit converges to 1/5, so the series converges.

1. No, that is a different Anonymous. I'm still not sure about my answer.

2. an+1 = 1/5^(n+1)
an = 1/5^n

an+1/an = 5^n/5^(n+1) = 1/5 indeed
so it converges
