ok starting at n=1 ((-1)^n-1)/(5n+1) so as far as i got is the (-1)^n-1 is pulled out as alternating leaving 1/(5n+1) and they want the sum of that

So the 1/2 is just clarifying an alternating series? I am completely lost on that problem. for the second i don't know what you mean either haha... all i know right now is it is an alternating problem... I have been trying to do these for like 3 hours to no success haha.. edit--- Well...

Ok i have a few here that i have no idea what to do b]1. Homework Statement [/b] Find the nth term in the series 1/2, 1/3, 2/9, 4/27, 8/81, 16/243 also \Sigma (-1)^n-1/ 5n+1 find the sum Urgent help neededdd ahha.. Thanks
