Halfway Between 13 and 109

When you ask "What number is halfway between 13 and 109?" 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=109.

Halfway Between Line

To find the number halfway between 13 and 109, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 109 into our formula, we get:

(13 + 109)/2 = 61

Thus, the number halfway between 13 and 109 is 61.

To check that our answer is correct, we subtract 13 from 61 and subtract 61 from 109 and compare the two numbers:

61 - 13 = 48
109 - 61 = 48

As you can see, the halfway number is 48 higher than 13 and 48 lower than 109. Therefore, our halfway between answer of 61 above is correct.
