Determine whether the following series converge or diverge.∞ ∑ (-1)^n (1-1/n) n=1

Answer 1

the first is\[\sum_1^\infty\frac1n(\frac65)^n\]?

Answer 2

I mean\[\sum_{n=1}^\infty\frac1n(\frac65)^n\]right??

Answer 3

if that's so...you can use several ways to determine its divergence...my suggestion use Cauchy's approach
