Halfway Between 15 and 787

When you ask "What number is halfway between 15 and 787?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=787.

Halfway Between Line

To find the number halfway between 15 and 787, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 787 into our formula, we get:

(15 + 787)/2 = 401

Thus, the number halfway between 15 and 787 is 401.

To check that our answer is correct, we subtract 15 from 401 and subtract 401 from 787 and compare the two numbers:

401 - 15 = 386
787 - 401 = 386

As you can see, the halfway number is 386 higher than 15 and 386 lower than 787. Therefore, our halfway between answer of 401 above is correct.
