9 and 16. So let one square number be aÃ‚Â², then the next number is (a+1)Ã‚Â². Now (a+1)Ã‚Â² = aÃ‚Â² + 2a + 1, then subtract aÃ‚Â² = 2a+1. Set this equal to 7:

• 2a+1=7
• 2a = 6
• a = 3

So aÃ‚Â² = 3Ã‚Â² = 9, and the next number is 4Ã‚Â² = 16.

The two square numbers that satisfy the condition are 16 and 9. When you subtract 9 from 16, the answer is 7.
