If the terms of the A.P. `sqrt(a-x),sqrt(x),sqrt(a+x)` are all in integers, `w h e r ea ,x >0,` then find the least composite value of `adot`

Explanation

To solve the problem, we need to find the least composite value of \( a \) such that the terms \( \sqrt{a-x}, \sqrt{x}, \sqrt{a+x} \) form an arithmetic progression (A.P.) and all terms are integers, given that \( x > 0 \).

### Step-by-Step Solution:

1. **Understanding the A.P. Condition**:
For three terms \( A, B, C \) to be in A.P., the condition is:
\[
2B = A + C
