Halfway Between 4 and 254

When you ask "What number is halfway between 4 and 254?" 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=254.

Halfway Between Line

To find the number halfway between 4 and 254, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 254 into our formula, we get:

(4 + 254)/2 = 129

Thus, the number halfway between 4 and 254 is 129.

To check that our answer is correct, we subtract 4 from 129 and subtract 129 from 254 and compare the two numbers:

129 - 4 = 125
254 - 129 = 125

As you can see, the halfway number is 125 higher than 4 and 125 lower than 254. Therefore, our halfway between answer of 129 above is correct.
