Halfway Between 15 and 331

When you ask "What number is halfway between 15 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=15 and Y=331.

Halfway Between Line

To find the number halfway between 15 and 331, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 331 into our formula, we get:

(15 + 331)/2 = 173

Thus, the number halfway between 15 and 331 is 173.

To check that our answer is correct, we subtract 15 from 173 and subtract 173 from 331 and compare the two numbers:

173 - 15 = 158
331 - 173 = 158

As you can see, the halfway number is 158 higher than 15 and 158 lower than 331. Therefore, our halfway between answer of 173 above is correct.
