Sum of first 25 terms in A.P. is 525, sum of next 25 terms is 725, what is the common difference?

Explanation

To find the common difference of the arithmetic progression (A.P.) given the sum of the first 25 terms and the sum of the next 25 terms, we can follow these steps:

### Step 1: Understand the given information
We know:
- The sum of the first 25 terms (S₁₅) = 525
- The sum of the next 25 terms (S₂₅) = 725

### Step 2: Use the formula for the sum of n terms in an A.P.
