Halfway Between 4 and 139




When you ask "What number is halfway between 4 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=4 and Y=139.



To find the number halfway between 4 and 139, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 139 into our formula, we get:

(4 + 139)/2 = 71.5

Thus, the number halfway between 4 and 139 is 71.5.


To check that our answer is correct, we subtract 4 from 71.5 and subtract 71.5 from 139 and compare the two numbers:

71.5 - 4 = 67.5
139 - 71.5 = 67.5

As you can see, the halfway number is 67.5 higher than 4 and 67.5 lower than 139. Therefore, our halfway between answer of 71.5 above is correct.
