Halfway Between 4 and 558

When you ask "What number is halfway between 4 and 558?" 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=558.

Halfway Between Line

To find the number halfway between 4 and 558, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 558 into our formula, we get:

(4 + 558)/2 = 281

Thus, the number halfway between 4 and 558 is 281.

To check that our answer is correct, we subtract 4 from 281 and subtract 281 from 558 and compare the two numbers:

281 - 4 = 277
558 - 281 = 277

As you can see, the halfway number is 277 higher than 4 and 277 lower than 558. Therefore, our halfway between answer of 281 above is correct.
