# FP1 - Summation of series watch

1. So I've been set a couple of questions for my homework. It's a summation question that I'm stuck on because I've never done a question that doesn't have an integer starting value

Anyone care to guide me? I don't need full solutions as of yet, but any little help would be appreciated.
2. Are you sure you've copied it out right? Because doesn't really make any sense. If it's supposed to be "r=1" rather than "r-1" on the bottom, then you need to expand the brackets and then sum as you would normally.

Are we still doing this whole 'simultaneous answers' thing?

Not my fault!
7. It must be r = 1.

Since I'm doing FM now, maybe I could get involved with the simultaneous answers thing that you guys have going on

Though my knowledge would be limited to strictly the basics of FP1
