Halfway Between 31 and 245

When you ask "What number is halfway between 31 and 245?" 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=245.

Halfway Between Line

To find the number halfway between 31 and 245, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 245 into our formula, we get:

(31 + 245)/2 = 138

Thus, the number halfway between 31 and 245 is 138.

To check that our answer is correct, we subtract 31 from 138 and subtract 138 from 245 and compare the two numbers:

138 - 31 = 107
245 - 138 = 107

As you can see, the halfway number is 107 higher than 31 and 107 lower than 245. Therefore, our halfway between answer of 138 above is correct.
