Homework Statement
I'm this series to see if it's convergent or divergent. I tried the root test, but it came out inclusive, and now I am trying to figure out if the ration test works. The only thing I'm asking which would be the right test for this.
Homework Equations
∞Ʃn=1 (2n+1)^n/(n^2n)
The Attempt at a Solution
[(2n+1)^n/(n^2)]^1/n
= (2n+1)/(n^2)
= [itex]\stackrel{}{lim n\rightarrow}[/itex]∞ (2n+1)/(n^2)
= 1/1
= 1
