Halfway Between 20 and 783

When you ask "What number is halfway between 20 and 783?" 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=783.

Halfway Between Line

To find the number halfway between 20 and 783, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 783 into our formula, we get:

(20 + 783)/2 = 401.5

Thus, the number halfway between 20 and 783 is 401.5.

To check that our answer is correct, we subtract 20 from 401.5 and subtract 401.5 from 783 and compare the two numbers:

401.5 - 20 = 381.5
783 - 401.5 = 381.5

As you can see, the halfway number is 381.5 higher than 20 and 381.5 lower than 783. Therefore, our halfway between answer of 401.5 above is correct.
