Halfway Between 42 and 720

When you ask "What number is halfway between 42 and 720?" 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=720.

Halfway Between Line

To find the number halfway between 42 and 720, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 42 and 720 into our formula, we get:

(42 + 720)/2 = 381

Thus, the number halfway between 42 and 720 is 381.

To check that our answer is correct, we subtract 42 from 381 and subtract 381 from 720 and compare the two numbers:

381 - 42 = 339
720 - 381 = 339

As you can see, the halfway number is 339 higher than 42 and 339 lower than 720. Therefore, our halfway between answer of 381 above is correct.
