The sum of the series
diverges and may be infinite, given the presence of both linear and reciprocal terms without specific constraints.
To find the sum of the series
, we need to simplify the expression and evaluate it.
First, let's decompose the fraction into two parts:
![\[ (3n^2 + 7)/(6n) = (3n^2)/(6n) + (7)/(6n) \]](https://img.qammunity.org/2024/formulas/mathematics/college/c3201xolpnx6kl475c0n6gehkc1r8ixlcr.png)
Now, simplify each term:
1.

2.
remains as is.
Combine the two terms:
![\[ (1)/(2)n + (7)/(6n) \]](https://img.qammunity.org/2024/formulas/mathematics/college/nak8c7070kagawk1qcbpqqqmsa0e8be3vs.png)
Now, we sum the series:
![\[ S = \sum_(n=1)^(\infty) \left((1)/(2)n + (7)/(6n)\right) \]](https://img.qammunity.org/2024/formulas/mathematics/college/pi7ttfji2j4cabmcnxgoy7zf2q9f9bor4p.png)
To find the sum of this series, we need to evaluate it. The series has both a linear and a reciprocal term, and its sum may not converge to a finite value. Therefore, it may diverge, and the sum may be infinite. Without a specific bound for the series, we cannot determine a finite sum.
In summary, the sum of the given series may be infinite, and more information or constraints on the series are needed for a definite answer.
