TODO: Write proof
Proof outline:
- Take [ilmath]k_1[/ilmath] to be the index of any point of the sequence in [ilmath]B_1(x)[/ilmath]
- Take [ilmath]k_2[/ilmath] to be any index AFTER [ilmath]k_1[/ilmath] of the sequence in the ball [ilmath]B_\frac{1}{2}(x)[/ilmath]
- ...
- Show the sequence [ilmath](x_{k_n})_{n=1}^\infty[/ilmath] converges to [ilmath]x[/ilmath]
We have exhibited a convergent subsequence, we're done.
