comment Test for convergence $\sum_{n = 2}^\infty \frac{1}{(n+1)\ln^2(n+1)}$
Why don't you just let your series start at 3 and replace n+1 with n? This question has been asked like 1 billion times here.

comment Finding expected value??
Yes you need to consider the 4th case. You have written down a lot of cases but what are their probabilities? Your 'approach' is not really maths. I suggest in each of the cases, you write down the probability of each case with the payout/loss...
