The digits of a positive integer, having three digits, are in A.P. and their sum is 15. The number obtained by reversing the digits is 594 less than the original number. Find the number.

Explanation

To solve the problem step by step, we will denote the digits of the three-digit number as follows:

Let the three digits be:
- First digit (hundreds place): \( a - t \)
- Second digit (tens place): \( a \)
- Third digit (units place): \( a + t \)

### Step 1: Set up the equations based on the problem statement.
