Question
![**Series Convergence with the Limit Comparison Test (LCT)**
**Problem Statement**
Using only the Limit Comparison Test (LCT), determine whether the following series converges or diverges:
\[ \sum_{n=1}^{\infty} \frac{n^3 + 2n^2 + n}{3n^4 + n^2 + 1} \]
Compare it to the following geometric series:
\[ \sum_{n=1}^{\infty} \frac{1}{n} \]
**Explanation of the Process**
- LCT requires finding a comparable series (usually simpler) whose behavior (convergence/divergence) is known.
- Typically, the most significant term in the numerator and denominator is used for comparison.
In this case, we compare the given series with a known series to determine its convergence properties.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F99289c38-7b50-427e-b7ea-7af0a1fcf022%2F9304ab9d-5b9b-4b06-9473-87f884ebf9e7%2Fw5rl9hs_processed.png&w=3840&q=75)
