Homework Statement
Suppose that {an} is a monotone decreasing sequence of positive numbers. Show that if the series an converges, then the lim(nan)=0.
Homework Equations
The Attempt at a Solution
I started the proof with the fact that since I know the sequence is monotone decreasing and the the series converges then the lim an=0 but I am not sure how to show that the lim nan=o.
any help would be greatly appreciated
