Exercise 4.10.1: Evaluating recursively defined sequences. About Give the first six terms of the following sequences. (a) The first term is 1 and the second term is 2. The rest of the terms are the product of the two preceding terms. (b) an = 1, a2 = 5, and an = 2-an-1 + 3. an-2 for n 23. (C) 91 = 2 and 92 =1. The rest of the terms are given by the formula On = n-gn-1 + 9n-2- (d) C1 = 4, C2 = 5, and cn = Cn-1 - Cn-2 for n23 (e) b1 = 1, b2 = 3, and bn = bn-1 - 7-bn-2 for n 23
