SUMMARY
The series \(\sum_{n=1}^{\infty} \frac{n+2^n}{n+3^n}\) diverges. The initial attempt to apply the divergence test was inconclusive, as the limit of the terms \(a_n = \frac{n+2^n}{n+3^n}\) approaches 0 as \(n\) approaches infinity. To determine convergence or divergence, alternative tests such as the Ratio Test or the Limit Comparison Test should be utilized for a definitive conclusion.
