Series
From Simple English Wikipedia, the free encyclopedia
A series is a group of several things that are all about the same thing, or are intentionally similar.
In mathematics, a series is several adding problems all together in one question. For example:
...As 1 plus 4 equals 5, then 5 plus 3 equals 8, then 8 plus 6 equals 14, then 14 plus 8 equals 22.
