Sequences are called infinite because they never stop---there is no last term.

If exists, then the sequence , , , , is said to converge. Otherwise, the sequence is said to diverge.

The statement means that as gets large, the difference between and gets arbitrarily small. No matter how large a positive integer you choose, the numbers in the sequence eventually get within of ; that is, there is a positive integer such that whenever .
