To determine whether the sequence \(-1, -\frac{3}{2}, -2, \frac{5}{2}, \ldots\) forms an arithmetic progression (AP), we need to check if the common difference between consecutive terms is constant. ### Step-by-Step Solution: 1. **Identify the terms of the sequence:** - Let \(a_1 = -1\) - Let \(a_2 = -\frac{3}{2}\) - Let \(a_3 = -2\) ...
