Halfway Between 20 and 787

When you ask "What number is halfway between 20 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=20 and Y=787.

Halfway Between Line

To find the number halfway between 20 and 787, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 787 into our formula, we get:

(20 + 787)/2 = 403.5

Thus, the number halfway between 20 and 787 is 403.5.

To check that our answer is correct, we subtract 20 from 403.5 and subtract 403.5 from 787 and compare the two numbers:

403.5 - 20 = 383.5
787 - 403.5 = 383.5

As you can see, the halfway number is 383.5 higher than 20 and 383.5 lower than 787. Therefore, our halfway between answer of 403.5 above is correct.
