What is the correct answer to guess a formula for tn as a summation written in expanded form, and use Theorem 5.2.1 to write it as a single fraction whose denominator is 2 given a recursively defined sequence?

Consider the following recursively defined sequence.
+ 3k + 1, for each integer k 2 1
tk = 'k - 1
to = 0
The steps below begin an iterative process to guess an explicit formula for the sequence.
to = 0
t = to
t, = t, + 3· 2 + 1 = (3 + 1) + 3· 2 + 1 = 3 + 3· 2 + 2
t, = t, + 3· 3 + 1 = (3 + 3· 2 + 2) + 3· 3 + 1 = 3 + 3· 2 + 3 · 3 + 3
+ 3.1 + 1 = 3 + 1
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 file with a maximum size of 1 MB.)
