There are three numbers that fit those requirements.
64 and 81
64
Every odd number greater than one is the difference of two squares. This includes all the odd prime numbers. To find the two numbers whose difference of squares equals a particular odd number, divide the odd number by 2. The two numbers are the integers immediately below and above that dividend. For example, 17 is the difference of two squares. Divide 17 by 2 and get 8.5. The two numbers are 8 and 9. 92 - 82 = 81 - 64 = 17.
There are several odd numbers between 42 and 64. One such is 61.

There are 7 odd numbers between 50 and 64. To find this, we first identify the odd numbers in the range, which are 51, 53, 55, 57, 59, 61, and 63. We can calculate the count by subtracting the first odd number (51) from the last odd number (63) and then adding 1 (63-51+1=13+1=7).
The sum of all odd numbers from 1 to 64 inclusive is 4,096
