Do the first five terms to understand the pattern. :|
or you could break it into two summations if i recall the rules correctly

We only went over sigma notation for like a week in AP Calc, so I don't remember how to do it at all.

I was never taught this in precalculus. Of course mine was summer school so it was quite chopped down.

that doesn't mean that you only work on sigma problems for a few minutes

Our teacher only briefly explained it, yeah, but we worked on homework that had to do with it for around a week.

that's your fault
anyway math doesn't work in such nice ways so you should do mental arithmetic to help mathematical progress in this country
