Justify whether it is true to say that ` -1, (-3)/(2), -2, (5)/(2), … ` Forms an AP as `a_(2)-a_(1)=a_(3)-a_(2)`.

Explanation

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 difference between consecutive terms is constant.

### Step 1: Identify the terms
Let:
- \( a_1 = -1 \)
- \( a_2 = -\frac{3}{2} \)
- \( a_3 = -2 \)
- \( a_4 = \frac{5}{2} \)
