Mark all the true statements about sequences of real numbers. If the limit superior of a bounded sequence equals the limit inferior, then the sequence converges. Every unbounded sequence has a divergent subsequence. If a sequence has no bounded subsequence, then the sequence diverges. If a sequence has no divergent subsequence, then the sequence converges. If a sequence is bounded above, then there is a subsequence that converges to the limit superior of the sequence.
