## Homework Equations

## The Attempt at a Solution

I'm a little confused on the "..." part... I used the ratio test and the numbers obviously cancel out, but I am not sure if the (2n+2)/(2n) part cancel out to just make (2n+2) on the top. This would make the limit equal to 2 and it would diverge. But I am not entirely sure if that's right...
