(1 point) For each of the recursively defined sequences given below, write out the next four terms of the sequence. (Hint: Take note of the index of the first term.) (a) ai = 8a 1 with a = 1 1, (b) bj = j(bj-1) with bo == == -3 -3, (c) ckck-1+2ck-2 with co = 1 and c = = -1 - 1, 1, 1 -1 -1 (d) dn = ndn-1-dn-2 with d = 1 and d = 3 1. 3. 1
