Halfway Between 13 and 89

When you ask "What number is halfway between 13 and 89?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=13 and Y=89.

Halfway Between Line

To find the number halfway between 13 and 89, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 89 into our formula, we get:

(13 + 89)/2 = 51

Thus, the number halfway between 13 and 89 is 51.

To check that our answer is correct, we subtract 13 from 51 and subtract 51 from 89 and compare the two numbers:

51 - 13 = 38
89 - 51 = 38

As you can see, the halfway number is 38 higher than 13 and 38 lower than 89. Therefore, our halfway between answer of 51 above is correct.
