(a) For which one of the following series is the ratio test inconclusive? (i) n=1∑∞5nn (ii) n=1∑∞n(−3)n+1 (iii) n=1∑∞1+n2n (iv) n=1∑∞nn! (b) Does the sequence whose nth term is an=arctannln(e+n1) converge and if so to what value? (i) No it diverges. (iii) Yes, it converges to 0 . (ii) Yes, it converges to π. (iv) Yes, it converges to π2.
