I am trying to test this series by the alternating series test:

n=1 to infinity

I don't really know how to find the limit or how to see if it is decreasing, any help would be greatly appreciated.

Thanks,

CC

So I basically have:

as n goes to infinity

which would equal zero

and decreasing because the first term is

1/1 then the second is 1/(2*1) and so on? - Apr 22nd 2010, 10:11 PMDrexel28
