Halfway Between 20 and 404

When you ask "What number is halfway between 20 and 404?" 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=404.

Halfway Between Line

To find the number halfway between 20 and 404, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 404 into our formula, we get:

(20 + 404)/2 = 212

Thus, the number halfway between 20 and 404 is 212.

To check that our answer is correct, we subtract 20 from 212 and subtract 212 from 404 and compare the two numbers:

212 - 20 = 192
404 - 212 = 192

As you can see, the halfway number is 192 higher than 20 and 192 lower than 404. Therefore, our halfway between answer of 212 above is correct.
