Halfway Between 31 and 787

When you ask "What number is halfway between 31 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=31 and Y=787.

Halfway Between Line

To find the number halfway between 31 and 787, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 787 into our formula, we get:

(31 + 787)/2 = 409

Thus, the number halfway between 31 and 787 is 409.

To check that our answer is correct, we subtract 31 from 409 and subtract 409 from 787 and compare the two numbers:

409 - 31 = 378
787 - 409 = 378

As you can see, the halfway number is 378 higher than 31 and 378 lower than 787. Therefore, our halfway between answer of 409 above is correct.
