Sequences and Series**

A sequence has a limit L, or converges to L, if. If such a number L does not exist, the sequence has no limit or diverges. Let be a sequence with and suppose that exists for every real number. Then the following cases apply. Case 1. Case 2. Sequence an infinite set of ordered numbers. 1, 4, 9, 16, 25,… is the sequence of perfect squares. ................
