(1) Determine whether the sequence converges or diverges. If the sequence converges, find its limit. n2 + 1 (a) (5 points) an = (b) (5 points) bn = en 2n2 + 3n + 1 n (2) Determine convergence or divergence of the series. If the series converges, find its sum. n n +1 (a) (5 points) (b) (5 points) n - 1 n= n=2
