Sep 5 comment Calculate the sum of the first N terms of the sequence Got it! Thank you. Answer seems to be $n/2(a_1 + a_{n})$ Sep 5 asked Calculate the sum of the first N terms of the sequence Sep 5 comment Closed form solution of a definite integral? No more help needed, I got it. Thank you! Sep 5 comment Closed form solution of a definite integral? Alright, thanks. Disregard what I had typed here before, I had gotten confused. Sep 5 comment Closed form solution of a definite integral? It's been a while since doing IBP, for the second one I ended up getting $-e^{-x}\(x^2 - 2x) - 2$, does that seem correct?
