Halfway Between 11 and 104

When you ask "What number is halfway between 11 and 104?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=11 and Y=104.

Halfway Between Line

To find the number halfway between 11 and 104, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 104 into our formula, we get:

(11 + 104)/2 = 57.5

Thus, the number halfway between 11 and 104 is 57.5.

To check that our answer is correct, we subtract 11 from 57.5 and subtract 57.5 from 104 and compare the two numbers:

57.5 - 11 = 46.5
104 - 57.5 = 46.5

As you can see, the halfway number is 46.5 higher than 11 and 46.5 lower than 104. Therefore, our halfway between answer of 57.5 above is correct.
