    1. The problem statement, all variables and given/known data

    If the series is 2/n^2 +4n+3

    2. Relevant equations


    After factorizing the Den who to find Sn ?

    3. The attempt at a solution

    I found S1 and S2 and S3 ....S6 and then how to find Sn (general form) ??

    You want to express it in partial fraction form. Like A/(x+a)+B/(x+b). Did you factorize the denominator?

    Oh, ya I am done with all the steps, except the last thing which is finding the Sn - general form.

    Then don't you notice that there's a term in a_(n+2) that cancels a term in a_(n). I wish you would show more of your work.
