Halfway Between 45 and 105

When you ask "What number is halfway between 45 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=45 and Y=105.

Halfway Between Line

To find the number halfway between 45 and 105, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 105 into our formula, we get:

(45 + 105)/2 = 75

Thus, the number halfway between 45 and 105 is 75.

To check that our answer is correct, we subtract 45 from 75 and subtract 75 from 105 and compare the two numbers:

75 - 45 = 30
105 - 75 = 30

As you can see, the halfway number is 30 higher than 45 and 30 lower than 105. Therefore, our halfway between answer of 75 above is correct.
