We construct two adjacent sequences that converge to the sum of a given convergent -series. In case of a divergent -series, lower and upper bounds of the th partial sum are constructed. In either case, we extend the results obtained by Hansheng and Lu (2005) to any integer . Some numerical examples are given.
