Halfway Between 13 and 787

When you ask "What number is halfway between 13 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=13 and Y=787.

Halfway Between Line

To find the number halfway between 13 and 787, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 787 into our formula, we get:

(13 + 787)/2 = 400

Thus, the number halfway between 13 and 787 is 400.

To check that our answer is correct, we subtract 13 from 400 and subtract 400 from 787 and compare the two numbers:

400 - 13 = 387
787 - 400 = 387

As you can see, the halfway number is 387 higher than 13 and 387 lower than 787. Therefore, our halfway between answer of 400 above is correct.
