When you ask "What number is halfway between 42 and 862?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=42 and Y=862.

To find the number halfway between 42 and 862, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 42 and 862 into our formula, we get:
(42 + 862)/2 = 452
Thus, the number halfway between 42 and 862 is 452.
To check that our answer is correct, we subtract 42 from 452 and subtract 452 from 862 and compare the two numbers:
452 - 42 = 410
862 - 452 = 410
As you can see, the halfway number is 410 higher than 42 and 410 lower than 862. Therefore, our halfway between answer of 452 above is correct.
