### Series Representation Problem

**Question:**

Which of the following represents the series?

\[ -12 + (-5) + 2 + 9 + 16 \]

**Choices:**

1. \[ \sum_{k=0}^{4} (-19 + 7k) \]
2. \[ \sum_{k=1}^{5} (-19 - 7k) \]
3. \[ \sum_{k=0}^{4} (-12 + 7k) \]
4. \[ \sum_{k=1}^{5} (-12 - 7k) \]

### Explanation:

To determine which option correctly represents the given series, we need to examine each series summation and compare it to the provided sequence.

Let's break down the provided series:
\[ -12, -5, 2, 9, 16 \]

This series can be represented as \(a_k\) where \(k\) starts at 0 or 1, and the differences between consecutive terms appear consistent, suggesting a possible arithmetic sequence.
