Halfway Between 23 and 331

When you ask "What number is halfway between 23 and 331?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=23 and Y=331.

Halfway Between Line

To find the number halfway between 23 and 331, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 23 and 331 into our formula, we get:

(23 + 331)/2 = 177

Thus, the number halfway between 23 and 331 is 177.

To check that our answer is correct, we subtract 23 from 177 and subtract 177 from 331 and compare the two numbers:

177 - 23 = 154
331 - 177 = 154

As you can see, the halfway number is 154 higher than 23 and 154 lower than 331. Therefore, our halfway between answer of 177 above is correct.
