Halfway Between 21 and 223

When you ask "What number is halfway between 21 and 223?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=21 and Y=223.

Halfway Between Line

To find the number halfway between 21 and 223, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 223 into our formula, we get:

(21 + 223)/2 = 122

Thus, the number halfway between 21 and 223 is 122.

To check that our answer is correct, we subtract 21 from 122 and subtract 122 from 223 and compare the two numbers:

122 - 21 = 101
223 - 122 = 101

As you can see, the halfway number is 101 higher than 21 and 101 lower than 223. Therefore, our halfway between answer of 122 above is correct.
