Question
Consider the following recursively defined sequence.
tk = tk -1 + 3k + 1, for each integer k > 1
to = 0
The steps below begin an iterative process to guess an explicit formula for the sequence.
to = 0
t = to + 3·1 + 1 = 3 + 1
t, = t, + 3 · 2 + 1 = (3 + 1) + 3 · 2 + 1 = 3 + 3· 2 + 2
t3 = t, + 3· 3 + 1 = (3 + 3· 2 + 2) + 3 · 3 + 1 = 3 + 3 ·2 + 3· 3 + 3
Continue the iteration process in a free response. Then guess a formula for t, as a summation written in expanded form, and use Theorem 5.2.1 to write it as a single fraction whose denominator is 2. (Submit a
