Halfway Between 9 and 105

When you ask "What number is halfway between 9 and 105?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=105.

Halfway Between Line

To find the number halfway between 9 and 105, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 105 into our formula, we get:

(9 + 105)/2 = 57

Thus, the number halfway between 9 and 105 is 57.

To check that our answer is correct, we subtract 9 from 57 and subtract 57 from 105 and compare the two numbers:

57 - 9 = 48
105 - 57 = 48

As you can see, the halfway number is 48 higher than 9 and 48 lower than 105. Therefore, our halfway between answer of 57 above is correct.
