Q1)

(x^n) / ((2^n)*ln(n)) = x is on the interval of -2 to 2. All of this is correct so far, however, I trouble evaluating the endpoints to see if they conditionally/absolute converges or diverges. According to the book answer, -2 conditionally converges, which I dont quite understand.

My question is, how do I evaluate the endpoints for convergence/divergence? I plugged the numbers in, but dont quite grasp how to proceed from there.
