Sum to n groups the following series
Need help fast..............Thanks a lot in advance.[/QUOTE]
Sorry..... I forgot to give brackets in the 3rd group........
NO.....It's not......but see....
I definitely see a pattern up there... and I belive it is possible to find the sum of the nth group and then the sum to n groups.........but I can't figure out how to do it........
And the chapter in which this sum is given is called "Geometrical Progression".......so I believe that even if the series as a whole is not in G.P. some part of it must be in G.P.
