Ʃ(x-->infinity, x>0) 11/(n(n+2))
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)
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?
