Halfway Between 31 and 345

When you ask "What number is halfway between 31 and 345?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=31 and Y=345.

Halfway Between Line

To find the number halfway between 31 and 345, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 345 into our formula, we get:

(31 + 345)/2 = 188

Thus, the number halfway between 31 and 345 is 188.

To check that our answer is correct, we subtract 31 from 188 and subtract 188 from 345 and compare the two numbers:

188 - 31 = 157
345 - 188 = 157

As you can see, the halfway number is 157 higher than 31 and 157 lower than 345. Therefore, our halfway between answer of 188 above is correct.
