How do I find the sum of this?

I got the sum of 2/3 ^n because its a Geometric sequence.

But the other part is tricky. I separated into two partial fractions but am stuck.Attachment 28824

How did you get to .5-1/(n+1)?

How do i complete this partial sum?

Thanks - Jul 14th 2013, 08:53 AMPlatoRe: Sum of convergent series
