How would you work out if these series converge or diverge? Problem 1 n=1 to infinity n!/10^n Problem 2 n=1 to infinity ((n-2)/n)^n Problem 3 n=1 to infinity (-2)^n/3^n

What exactly are you having troubles with? You are already told which tests to use. For example, the first one. Let . Then:
still not sure how to do the third problem though....can't use root test because of the negative term. There too many tests....
