Subsequences and Bounded Sequences - 12

In this lecture, we’ll dive deeper into our study of sequences. First we’ll study the properties of subsequences (that is, infinite subsets of sequences) to learn when and how they might converge. We’ll see what additional conditions are necessary to guarantee that a bounded sequence converges.
