When you ask "What number is halfway between 22 and 457?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=22 and Y=457.

To find the number halfway between 22 and 457, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 22 and 457 into our formula, we get:
(22 + 457)/2 = 239.5
Thus, the number halfway between 22 and 457 is 239.5.
To check that our answer is correct, we subtract 22 from 239.5 and subtract 239.5 from 457 and compare the two numbers:
239.5 - 22 = 217.5
457 - 239.5 = 217.5
As you can see, the halfway number is 217.5 higher than 22 and 217.5 lower than 457. Therefore, our halfway between answer of 239.5 above is correct.
