Halfway Between 4 and 125

When you ask "What number is halfway between 4 and 125?" 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=125.

Halfway Between Line

To find the number halfway between 4 and 125, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 125 into our formula, we get:

(4 + 125)/2 = 64.5

Thus, the number halfway between 4 and 125 is 64.5.

To check that our answer is correct, we subtract 4 from 64.5 and subtract 64.5 from 125 and compare the two numbers:

64.5 - 4 = 60.5
125 - 64.5 = 60.5

As you can see, the halfway number is 60.5 higher than 4 and 60.5 lower than 125. Therefore, our halfway between answer of 64.5 above is correct.
