Calculus 2: Sigma(n=1,infinity) 1/(3n-1)^2

Question

Sigma(n=1,infinity) 1/(3n-1)²

a) Name the series test(s)

b) Check all conditions for the series test(s) named in part (a)

c) Perform the series test(s) to determine whether the series is convergent or divergent.

Answer 1

I am not sure what is wanted here, but the series is convergent by the so-called "p test" which tells that

1/n^p converges for p>1.
