Sequences and Series

A sequence can be described as a list of objects, events, or numbers that come one after the other, that is, a list of things given in some definite order. Each object in the list is called a term of the sequence. Where no last term is indicated, is understood to be an infinite sequence. The three dots is called an ellipsis amd indicates that succeeding terms follow the same pattern as that set by the terms given. The elements in the range of a sequence are simply the terms of the sequence. The nth term f(n)=an is also called the general term of the sequence.
