1. The first 10 terms of a. for each sequence are given below. a. a. = n:〈a1,〉 = 〈1, 3, 6, 2, 7, 1, 8, 16, 7, 17, ...〉 b. an = n+1:(a′n) = (2, 5, 1, 6, 12, 5, 13, 4, 14, 3, …) c. an = n2 :(a′n) = (1, 5, 14, 30, 5, 41, 90, 26, 107, 7,…) d. an = 2n-1 :(a′n) = (1, 3, 7, 15, 31, 63, 127, 255, 511, 1023, …) e. a. = F,,:〈a′n〉 = (1, 2, 4, 1, 6, 14, 1, 22, 56, 1, …)。
