Halfway Between 45 and 110

When you ask "What number is halfway between 45 and 110?" 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=110.

Halfway Between Line

To find the number halfway between 45 and 110, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 110 into our formula, we get:

(45 + 110)/2 = 77.5

Thus, the number halfway between 45 and 110 is 77.5.

To check that our answer is correct, we subtract 45 from 77.5 and subtract 77.5 from 110 and compare the two numbers:

77.5 - 45 = 32.5
110 - 77.5 = 32.5

As you can see, the halfway number is 32.5 higher than 45 and 32.5 lower than 110. Therefore, our halfway between answer of 77.5 above is correct.
