Least Upper Bound and Greatest Lower Bound

In this video, I pay most of my attention to the Least Upper Bound Axiom, but try to give mention to the Greatest Lower Bound. The intent is to prove that a bounded, increasing sequence of real numbers has a finite limit. This idea is at the heart of why the various infinite series, of positive terms, either converge or diverge.

First time I understood LUB.

Thank you.
