Use the nth-Term Test for divergence to show that the series is divergent, or state that the test is inconclusive. 14) Σ n=1 COS 5 n 14) A) converges, 1 B) converges, 5 C) diverges D) inconclusive 7 Determine if the series converges or diverges. If the series converges, find its sum. 15) - √n+ n=1 A) converges; - B) converges; C) converges; D) diverges 15)
