Halfway Between 23 and 80

When you ask "What number is halfway between 23 and 80?" 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=80.

Halfway Between Line

To find the number halfway between 23 and 80, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 23 and 80 into our formula, we get:

(23 + 80)/2 = 51.5

Thus, the number halfway between 23 and 80 is 51.5.

To check that our answer is correct, we subtract 23 from 51.5 and subtract 51.5 from 80 and compare the two numbers:

51.5 - 23 = 28.5
80 - 51.5 = 28.5

As you can see, the halfway number is 28.5 higher than 23 and 28.5 lower than 80. Therefore, our halfway between answer of 51.5 above is correct.
