Halfway Between 15 and 223

When you ask "What number is halfway between 15 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=15 and Y=223.

Halfway Between Line

To find the number halfway between 15 and 223, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 223 into our formula, we get:

(15 + 223)/2 = 119

Thus, the number halfway between 15 and 223 is 119.

To check that our answer is correct, we subtract 15 from 119 and subtract 119 from 223 and compare the two numbers:

119 - 15 = 104
223 - 119 = 104

As you can see, the halfway number is 104 higher than 15 and 104 lower than 223. Therefore, our halfway between answer of 119 above is correct.
