A limit point is a point at which a subsequence of the sequence converges.

Yes:

1,1,2,1,2,3,1,2,3,4,1,2,3,4,5,1,2,3,4,5,6....
the constant sequence n,n,n,n,... is a subsequence of this sequence for every natural number n.

A convergent sequence has one limit point. Suppose than a_n has a,b as limit points. Let a-b/2=epsilon. If an converges, eventually a_n is within epsilon of its limit, but then it is more than epsilon of one of a,b, (say a), then a cannot be a limit point.

It can be "made" true for certain divergent sequences. However I doubt there are such convergent sequences
