Halfway Between 45 and 558

When you ask "What number is halfway between 45 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=45 and Y=558.

Halfway Between Line

To find the number halfway between 45 and 558, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 558 into our formula, we get:

(45 + 558)/2 = 301.5

Thus, the number halfway between 45 and 558 is 301.5.

To check that our answer is correct, we subtract 45 from 301.5 and subtract 301.5 from 558 and compare the two numbers:

301.5 - 45 = 256.5
558 - 301.5 = 256.5

As you can see, the halfway number is 256.5 higher than 45 and 256.5 lower than 558. Therefore, our halfway between answer of 301.5 above is correct.
