The expression in the image appears to be the following:

\[
-2 + e^{-4\gamma} \sum_{k=1}^{\infty} \frac{e^{\frac{k}{4}} k}{k + 4}
\]

Where:
- \( -2 \) is a constant.
- \( e^{-4\gamma} \) represents an exponential decay factor involving Euler's constant \( \gamma \).
- The summation goes from \( k = 1 \) to infinity.
- Inside the summation, the general term is \( \frac{e^{\frac{k}{4}} k}{k + 4} \).

This looks like a series, but to solve or evaluate it, we would need to explore convergence and possibly attempt simplifications for large values of \( k \). Let me break this down step by step to see if it's convergent or if there's a known form for this summation.

### Step-by-step approach:

1. **Exponential term analysis**:
   Each term in the sum involves \( e^{k/4} \), which grows quite quickly as \( k \) increases, but this is tempered by the denominator \( k + 4 \).

2. **Behavior of the summation**:
   As \( k \to \infty \), the denominator \( k + 4 \) behaves approximately as \( k \), so the terms look like \( \frac{e^{k/4} k}{k} = e^{k/4} \), which grows exponentially.

3. **Convergence analysis**:
   Given that \( e^{k/4} \) grows exponentially and is not tempered by a fast-decaying term, this sum appears to diverge. In fact, since each term grows exponentially, the infinite series likely diverges as well, implying that the whole expression does not converge.

Would you like me to perform a detailed analysis of each step or explore possible approximations for this type of sum? Let me know if you have further questions!
