Halfway Between 40 and 687

When you ask "What number is halfway between 40 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=40 and Y=687.

Halfway Between Line

To find the number halfway between 40 and 687, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 687 into our formula, we get:

(40 + 687)/2 = 363.5

Thus, the number halfway between 40 and 687 is 363.5.

To check that our answer is correct, we subtract 40 from 363.5 and subtract 363.5 from 687 and compare the two numbers:

363.5 - 40 = 323.5
687 - 363.5 = 323.5

As you can see, the halfway number is 323.5 higher than 40 and 323.5 lower than 687. Therefore, our halfway between answer of 363.5 above is correct.
