Halfway Between 80 and 558

When you ask "What number is halfway between 80 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=80 and Y=558.

Halfway Between Line

To find the number halfway between 80 and 558, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 558 into our formula, we get:

(80 + 558)/2 = 319

Thus, the number halfway between 80 and 558 is 319.

To check that our answer is correct, we subtract 80 from 319 and subtract 319 from 558 and compare the two numbers:

319 - 80 = 239
558 - 319 = 239

As you can see, the halfway number is 239 higher than 80 and 239 lower than 558. Therefore, our halfway between answer of 319 above is correct.
