Halfway Between 100 and 404

When you ask "What number is halfway between 100 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=100 and Y=404.

Halfway Between Line

To find the number halfway between 100 and 404, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 404 into our formula, we get:

(100 + 404)/2 = 252

Thus, the number halfway between 100 and 404 is 252.

To check that our answer is correct, we subtract 100 from 252 and subtract 252 from 404 and compare the two numbers:

252 - 100 = 152
404 - 252 = 152

As you can see, the halfway number is 152 higher than 100 and 152 lower than 404. Therefore, our halfway between answer of 252 above is correct.
