Halfway Between 12 and 558

When you ask "What number is halfway between 12 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=12 and Y=558.

Halfway Between Line

To find the number halfway between 12 and 558, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 558 into our formula, we get:

(12 + 558)/2 = 285

Thus, the number halfway between 12 and 558 is 285.

To check that our answer is correct, we subtract 12 from 285 and subtract 285 from 558 and compare the two numbers:

285 - 12 = 273
558 - 285 = 273

As you can see, the halfway number is 273 higher than 12 and 273 lower than 558. Therefore, our halfway between answer of 285 above is correct.
