Each bounded sequence of numbers contains a convergent subsequence. The theorem applies both to real and complex numbers. It can be generalized to include more-general objects, e.g. any bounded infinite set in 
-dimensional Euclidean space has at least one limit point in that space. There exist analogues of this theorem for even more-general spaces.
The theorem was demonstrated by B. Bolzano [1]; it was later also independently deduced by K. Weierstrass.
