1. Problem Description
The problem asks us to analyze the sequence . We need to find the first few terms of the sequence, determine if it converges or diverges, and if it converges, find the limit as approaches infinity.
2. Solution Steps
First, let's find the first few terms of the sequence:
Now, let's analyze the convergence of the sequence. We have . We can rewrite this as . We know that for all . Therefore, we have:
.
As approaches infinity, also approaches infinity. Therefore, and .
By the squeeze theorem, since and and , we have:
.
Therefore, the sequence converges to
0.
3. Final Answer
The first few terms are approximately: 0.3096, 0.1231, 0.0142, -0.0149, -0.0128, -0.
0
0
0
9. The sequence converges.
The limit of the sequence is
0.
