Please help! $\lim_{n \to \infty} (-1)^{n+1} (n+1)^2$ this is the limit of an alternating sequence. the sequence is 4, -9, 16, -25 and I think I set it up right but if I didn't please tell me how it should be set up. I'm supposed to find the limit of the sequence. The absolute value of the terms approaches infinity, but since they're alternating positive and negative I'm not sure if the limit is DNE, infinity, or +or- infinity
