Solution: Using a Recursively Defined Series In Exercises 7782, the terms of a series
Chapter 9, Problem 80(choose chapter or problem)
Using a Recursively Defined Series In Exercises 77-82, the terms of a series \(\sum_{n=1}^{\infty} a_{n}\) are defined recursively. Determine the convergence or divergence of the series. Explain your reasoning.
\(a_{1}=\frac{1}{5}, a_{n+1}=\frac{\cos n+1}{n} a_{n}\)
Text Transcription:
Sum_n=1^infinity a_n
a_1=1/5, a_n+1 = cos n+1/n a_n
