Let \{x_n\}_{n=1}^\infty be a bounded sequence of real numbers and denote by \\ $S \subset \mathbb{R}$ the set of all sub - sequential limits of \{x_n\}_{n=1}^\infty. \\ Then $S$ is: \\ compact. \\ open \\ a single point. \\ infinite.

We know that the set S = {1/n: n ∈ N} is not compact because 0 is a limit point of S that is not in S. To see the non-compactness of S in another way, find an open cover of S that does not have a finite subcover!
