Halfway Between 75 and 687

When you ask "What number is halfway between 75 and 687?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=75 and Y=687.

Halfway Between Line

To find the number halfway between 75 and 687, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 75 and 687 into our formula, we get:

(75 + 687)/2 = 381

Thus, the number halfway between 75 and 687 is 381.

To check that our answer is correct, we subtract 75 from 381 and subtract 381 from 687 and compare the two numbers:

381 - 75 = 306
687 - 381 = 306

As you can see, the halfway number is 306 higher than 75 and 306 lower than 687. Therefore, our halfway between answer of 381 above is correct.
