Halfway Between 20 and 800

When you ask "What number is halfway between 20 and 800?" 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=800.

Halfway Between Line

To find the number halfway between 20 and 800, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 800 into our formula, we get:

(20 + 800)/2 = 410

Thus, the number halfway between 20 and 800 is 410.

To check that our answer is correct, we subtract 20 from 410 and subtract 410 from 800 and compare the two numbers:

410 - 20 = 390
800 - 410 = 390

As you can see, the halfway number is 390 higher than 20 and 390 lower than 800. Therefore, our halfway between answer of 410 above is correct.
