P n=1 an is divergent, then it must always be the case that (a) lim n (b) lim n an 6= 0. an = 0. (c) an 0 for all n. (d) none of the above. 1 r n=0 (a) r < 1. (b) r > 1. (c) |r| < 1. (d) none of the above. (tf) true/false, answer on the last page of the quiz. P n=1 an is convergent and |a| < |b|, then. P n=1 bn is convergent: true or false: if an 6= 0 for all n and. 1 an is divergent. (sa) short answer questions, marks only awarded for a correct nal answer, you do not need to show any work.
