Sequences - Increasing, decreasing, bounded and monotonic sequences

In this video we are going to look at increasing, decreasing, bounded and monotonic sequences and a theorem for convergence of a sequence.

[ConceptualCalculus]

If {an} is monotone and |an| < M for all n then {an} converges--but there is no reason to assume that the limit of {an} is M or even "very close to M" as you say. Consider the sequence an = 1 - (1/n). It is monotonic (increasing) and bounded by 100. That is, for all values of N, |an| < 100. But the limit is 1, not 100.
