Halfway Between 9 and 787

When you ask "What number is halfway between 9 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=9 and Y=787.

Halfway Between Line

To find the number halfway between 9 and 787, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 787 into our formula, we get:

(9 + 787)/2 = 398

Thus, the number halfway between 9 and 787 is 398.

To check that our answer is correct, we subtract 9 from 398 and subtract 398 from 787 and compare the two numbers:

398 - 9 = 389
787 - 398 = 389

As you can see, the halfway number is 389 higher than 9 and 389 lower than 787. Therefore, our halfway between answer of 398 above is correct.
