Halfway Between 42 and 872

When you ask "What number is halfway between 42 and 872?" 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=872.

Halfway Between Line

To find the number halfway between 42 and 872, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 42 and 872 into our formula, we get:

(42 + 872)/2 = 457

Thus, the number halfway between 42 and 872 is 457.

To check that our answer is correct, we subtract 42 from 457 and subtract 457 from 872 and compare the two numbers:

457 - 42 = 415
872 - 457 = 415

As you can see, the halfway number is 415 higher than 42 and 415 lower than 872. Therefore, our halfway between answer of 457 above is correct.
