### Convergence

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.

The limit operator is just an excuse for doing something you know you can'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.

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
