Sequence is a bunch of numbers having some relationships but the sum of several terms of a sequence is called a series. –  Gigili May 28 '12 at 14:37
what about finite sequence and series? –  Kns May 28 '12 at 14:39
What about them? –  Gigili May 28 '12 at 14:40
You could find some good explanations by googling. –  Gigili May 28 '12 at 14:53
I'm gonna go with "not constructive"... –  The Chaz 2.0 May 28 '12 at 14:57

There is no difference from general point of view. The point is that for each series $\sum_{k=1}^\infty a_k$ one can consider the sequence of its partial sums $s_n=\sum_{k=1}^na_k$, and for each sequence $\{s_k\}_{k=1}^\infty$ the series $\sum_{k=1}^\infty a_k$ can be considered where $a_1=s_1,\,a_k=s_{k}-s_{k-1}$.
