1/sqrt(n) - 1/sqrt(n+1)
is there a quick way to find out the sum of the series where n=1 + n=2 + n=3, all the way up to...99?
Couldn't you have replied to your own thread at http://www.mathhelpforum.com/math-he...-real-one.html ?
for n = 1, 2, 3,... 99
See what happens when you plug in the numbers:
Everything cancels except the first and last terms!
