Halfway Between 23 and 138

When you ask "What number is halfway between 23 and 138?" 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=138.

Halfway Between Line

To find the number halfway between 23 and 138, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 23 and 138 into our formula, we get:

(23 + 138)/2 = 80.5

Thus, the number halfway between 23 and 138 is 80.5.

To check that our answer is correct, we subtract 23 from 80.5 and subtract 80.5 from 138 and compare the two numbers:

80.5 - 23 = 57.5
138 - 80.5 = 57.5

As you can see, the halfway number is 57.5 higher than 23 and 57.5 lower than 138. Therefore, our halfway between answer of 80.5 above is correct.
