Halfway Between 45 and 139

When you ask "What number is halfway between 45 and 139?" 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=139.

Halfway Between Line

To find the number halfway between 45 and 139, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 139 into our formula, we get:

(45 + 139)/2 = 92

Thus, the number halfway between 45 and 139 is 92.

To check that our answer is correct, we subtract 45 from 92 and subtract 92 from 139 and compare the two numbers:

92 - 45 = 47
139 - 92 = 47

As you can see, the halfway number is 47 higher than 45 and 47 lower than 139. Therefore, our halfway between answer of 92 above is correct.
