Question
![**Problem Description:**
Write an expression for the \( n \)-th term of the sequence. (Your formula should work for \( n = 1, 2, \ldots \))
\[ \frac{1}{2}, \frac{1}{3}, \frac{1}{7}, \frac{1}{25}, \frac{1}{121}, \ldots \]
\[ a_n = \]
Determine whether the sequence you have chosen converges or diverges.
**Guidance:**
This problem requires you to find a pattern in the denominators of the given sequence to derive a general expression for the \( n \)-th term, \( a_n \). Check the sequence for any established mathematical patterns or identify if each denominator can be connected through a certain mathematical formula. Once you have your expression, apply convergence tests to determine if the sequence converges or diverges as \( n \) approaches infinity.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff3ee3651-1b97-4c6f-9df6-e9830d97e7c2%2Fd19f7c26-55d7-44cf-8c8e-676018db0f76%2Fmv50nh9_processed.png&w=3840&q=75)
