Homework Statement
The problem is part of a review and we are only to determine if the series converges or diverges by any test, and state the test.
##\sum_{n=1}^\infty(\frac{k}{k+1})^k##
My work so far
I know that the root test gives an inconclusive answer and from there I moved to looking at the series like a geometric. I have no idea if this actually works and could use input.
$$\sum_{n=1}^\infty(\frac{k}{k+1})^k$$ geometric series ##r=\frac{k}{k+1}##
$$\lim_{k\rightarrow\infty}{\frac{k}{k+1}}=1$$ r>0 series converges.
Does this work ? I keep second guessing myself but I can't find another test that works.
