Halfway Between 23 and 139

When you ask "What number is halfway between 23 and 139?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=23 and Y=139.

Halfway Between Line

To find the number halfway between 23 and 139, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 23 and 139 into our formula, we get:

(23 + 139)/2 = 81

Thus, the number halfway between 23 and 139 is 81.

To check that our answer is correct, we subtract 23 from 81 and subtract 81 from 139 and compare the two numbers:

81 - 23 = 58
139 - 81 = 58

As you can see, the halfway number is 58 higher than 23 and 58 lower than 139. Therefore, our halfway between answer of 81 above is correct.
