Halfway Between 11 and 787

When you ask "What number is halfway between 11 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=11 and Y=787.

Halfway Between Line

To find the number halfway between 11 and 787, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 787 into our formula, we get:

(11 + 787)/2 = 399

Thus, the number halfway between 11 and 787 is 399.

To check that our answer is correct, we subtract 11 from 399 and subtract 399 from 787 and compare the two numbers:

399 - 11 = 388
787 - 399 = 388

As you can see, the halfway number is 388 higher than 11 and 388 lower than 787. Therefore, our halfway between answer of 399 above is correct.
