How to solve a recursive sequence

WebAll solutions to the recurrence relation a n + 1 = s a n + t with s ≠ 1 have the form: a n = c 1 s n + c 2, where c 1 and c 2 are specific constants. In the problem s = 1 / 2. Therefore, a n = c 1 ( 1 / 2) n + c 2. Taking into account a 0 = 4 and a 1 = 3, one can obtain c 1 = 2 = c 2. Hence, a n = 2 1 − n + 2.
