Question

My Last one... Determine whether the series converge absolutely, converge conditionally or diverge.
SUM (-1)^n/((sqrt(2))^3n)

Answer 1

as n =0 to inf

Answer 2

\[\sum_{0}^{\inf} (-1)^{n}/(\sqrt{2})^{3n}\]

Answer 3

Taking the Abs limit i get 1/inf = 0 so I know it converges.

Answer 4

I still need to know whether it converges absolutely or conditionally though...
