Finding the general term Sn for the series 2/(n²+4n+3)

[remaan]

Homework Statement

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

Homework Equations

After factorizing the Den who to find Sn ?

The Attempt at a Solution

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

 

[Dick]

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

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

 

[Dick]

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.
