Are there tests to see if a sequence (not series) converges?

There are 10 kinds of people in the world,people who understand binary and people who don't.

Hi;

You have to determine the limit of the general term.

Generally if a sequence has a limit it is convergent, if not then it is divergent.

A bit more rigorous, if the limit of a sequence exists or is finite then the sequence converges, If the limit does not exist or is infinite then the sequence diverges.
