Halfway Between 13 and 331

When you ask "What number is halfway between 13 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=13 and Y=331.

Halfway Between Line

To find the number halfway between 13 and 331, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 331 into our formula, we get:

(13 + 331)/2 = 172

Thus, the number halfway between 13 and 331 is 172.

To check that our answer is correct, we subtract 13 from 172 and subtract 172 from 331 and compare the two numbers:

172 - 13 = 159
331 - 172 = 159

As you can see, the halfway number is 159 higher than 13 and 159 lower than 331. Therefore, our halfway between answer of 172 above is correct.
