26. Determine whether the telescoping series converges or diverges. If the series
converges, find the sum. (You may need to rewrite the terms in telescoping
form first.)
![The image contains a mathematical series expression:
\[ 26. \quad \sum_{n=2}^{\infty} \frac{2}{n^2 - 1} \]
This expression represents the infinite series starting from \( n = 2 \) to infinity. Each term in the series is given by the formula:
\[ \frac{2}{n^2 - 1} \]
Here, \( n^2 - 1 \) is a difference of squares, which can be factored as \( (n-1)(n+1) \). This expression forms the basis for evaluating or transforming the series further.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5c7a7557-48de-4534-a80a-48391c1bf13e%2F89bb732f-37b3-48a9-88fd-2f3102df7a95%2Fk20v1o_processed.png&w=3840&q=75)
