Question
**Problem Statement:**

Determine whether the series is convergent or divergent by expressing \( s_n \) as a telescoping sum (as in Example 8).

\[ \sum_{n=1}^{\infty} \frac{15}{n(n+3)} \]

**Solution Options:**

- [x] Convergent
- [ ] Divergent

**Next Steps:**

If it is convergent, find its sum. (If the quantity diverges, enter DIVERGES.)

Entered Answer: \(\frac{11}{6}\) ❌

---

**Explanation:**
In this problem, the series is identified as convergent, represented by the checked box under the "convergent" option. However, the attempt to find the sum, \(\frac{11}{6}\), is incorrect. The task involves expressing the series using a telescoping sum, which simplifies the process of determining convergence and finding the correct sum if it exists.
