## Homework Statement

Ʃ(x-->infinity, x>0) 11/(n(n+2))

## Homework Equations

## The Attempt at a Solution

I am not quite sure what to do, i think that i am supposed to put it into partial fractions.

i changed it to the form 11/(n^2+2n)

--> 11/((n+1)(n+1)-1))

--> 11/((n+1)^2-1)

Now i am kind of stuck, i know the answer is 33/4 but i am not sure how i can get to it.

Can anyone please help me out?

Also, can this be considered a geometric series?
