When you ask "What number is halfway between 7 and 64?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=7 and Y=64.

To find the number halfway between 7 and 64, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 7 and 64 into our formula, we get:
(7 + 64)/2 = 35.5
Thus, the number halfway between 7 and 64 is 35.5.
To check that our answer is correct, we subtract 7 from 35.5 and subtract 35.5 from 64 and compare the two numbers:
35.5 - 7 = 28.5
64 - 35.5 = 28.5
As you can see, the halfway number is 28.5 higher than 7 and 28.5 lower than 64. Therefore, our halfway between answer of 35.5 above is correct.
