When you ask "What number is halfway between 82 and 722?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=82 and Y=722.

To find the number halfway between 82 and 722, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 82 and 722 into our formula, we get:
(82 + 722)/2 = 402
Thus, the number halfway between 82 and 722 is 402.
To check that our answer is correct, we subtract 82 from 402 and subtract 402 from 722 and compare the two numbers:
402 - 82 = 320
722 - 402 = 320
As you can see, the halfway number is 320 higher than 82 and 320 lower than 722. Therefore, our halfway between answer of 402 above is correct.
