Halfway Between 45 and 123

When you ask "What number is halfway between 45 and 123?" 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=123.

Halfway Between Line

To find the number halfway between 45 and 123, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 123 into our formula, we get:

(45 + 123)/2 = 84

Thus, the number halfway between 45 and 123 is 84.

To check that our answer is correct, we subtract 45 from 84 and subtract 84 from 123 and compare the two numbers:

84 - 45 = 39
123 - 84 = 39

As you can see, the halfway number is 39 higher than 45 and 39 lower than 123. Therefore, our halfway between answer of 84 above is correct.
