Halfway Between 20 and 801

When you ask "What number is halfway between 20 and 801?" 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=801.

Halfway Between Line

To find the number halfway between 20 and 801, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 801 into our formula, we get:

(20 + 801)/2 = 410.5

Thus, the number halfway between 20 and 801 is 410.5.

To check that our answer is correct, we subtract 20 from 410.5 and subtract 410.5 from 801 and compare the two numbers:

410.5 - 20 = 390.5
801 - 410.5 = 390.5

As you can see, the halfway number is 390.5 higher than 20 and 390.5 lower than 801. Therefore, our halfway between answer of 410.5 above is correct.
