What is

infinity

∑ (-1)^n

n=0

What does this mean and why?

The bold is the equation. Cannot format with equation maker from microsoft word for this problem. Please let me know if there is any confusion.

the terms converging to 0 doesn’t imply the series converges, as the harmonic series gives a counterexample to that. The term test can be used to show that the following series don’t converge X n n + 1 X n! n2 X(−1)n n 2n + 1

I'm confused with your mathamatical expression at the end of your response. Could you clarify it for me please?
