Halfway Between 31 and 275

When you ask "What number is halfway between 31 and 275?" 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=275.

Halfway Between Line

To find the number halfway between 31 and 275, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 275 into our formula, we get:

(31 + 275)/2 = 153

Thus, the number halfway between 31 and 275 is 153.

To check that our answer is correct, we subtract 31 from 153 and subtract 153 from 275 and compare the two numbers:

153 - 31 = 122
275 - 153 = 122

As you can see, the halfway number is 122 higher than 31 and 122 lower than 275. Therefore, our halfway between answer of 153 above is correct.
