When you subtract one square number from the next higher square what is the difference?
The difference is an odd number (2n+1), as shown from (n+1)² = n² + 2n + 1, which as you can see is a linear progression of odd numbers, either n or (n+1) being odd. 4-1 = 3 9-4 = 5 16-9 = 7 25-16 = 9 36-25 = 11 49-36 = 13 64-49 = 15 81-64 = 17 The difference between any two ODD squares is always a multiple of 8, where for an odd n, and odd n+2, the difference in their squares is the sum of the two intervening differences, and can be expressed as 4n+4. 1) 9-1 = 8 3) 25- 9 = 16 5) 49-25 = 24 7) 81-49 = 32
