Halfway Between 20 and 222

When you ask "What number is halfway between 20 and 222?" 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=222.

Halfway Between Line

To find the number halfway between 20 and 222, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 222 into our formula, we get:

(20 + 222)/2 = 121

Thus, the number halfway between 20 and 222 is 121.

To check that our answer is correct, we subtract 20 from 121 and subtract 121 from 222 and compare the two numbers:

121 - 20 = 101
222 - 121 = 101

As you can see, the halfway number is 101 higher than 20 and 101 lower than 222. Therefore, our halfway between answer of 121 above is correct.
