Halfway Between 90 and 787

When you ask "What number is halfway between 90 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=90 and Y=787.

Halfway Between Line

To find the number halfway between 90 and 787, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 787 into our formula, we get:

(90 + 787)/2 = 438.5

Thus, the number halfway between 90 and 787 is 438.5.

To check that our answer is correct, we subtract 90 from 438.5 and subtract 438.5 from 787 and compare the two numbers:

438.5 - 90 = 348.5
787 - 438.5 = 348.5

As you can see, the halfway number is 348.5 higher than 90 and 348.5 lower than 787. Therefore, our halfway between answer of 438.5 above is correct.
