Monotone Decreasing Sequence Of Positive Numbers Calculus Homework Help

Show that the convergence of a series is not affected by changing a finite number of its terms. (The value of the sum may be changed)?

Suppose that ( a_n) is a monotone decreasing sequence of positive numbers. Show that if the series (sum (a_n)) converges, then the lim (na_n) = 0. Is the converges true?
