I need to find the interval and radius of convergence of the power series.

I forgot which steps I should take to solve this, Any & all help is appreciated!

∞

∑ ((-1^n)*(x^n)) / ((n+1)(n+2))

n=1

Just for the record, this is not homework, it is part of the review for my final exam (which is in 2 hours!) D:

It can be found at this address, in case you doubt me.

If you know how to solve this, I have a question:

How do you know which values to test out for convergence (in order to find the interval)?

Is this just a random test, or are there steps to take to figure out possible values in the interval?

Thanks in advance!
