Halfway Between 87 and 787

When you ask "What number is halfway between 87 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=87 and Y=787.

Halfway Between Line

To find the number halfway between 87 and 787, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 87 and 787 into our formula, we get:

(87 + 787)/2 = 437

Thus, the number halfway between 87 and 787 is 437.

To check that our answer is correct, we subtract 87 from 437 and subtract 437 from 787 and compare the two numbers:

437 - 87 = 350
787 - 437 = 350

As you can see, the halfway number is 350 higher than 87 and 350 lower than 787. Therefore, our halfway between answer of 437 above is correct.
