Halfway Between 40 and 558

When you ask "What number is halfway between 40 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=40 and Y=558.

Halfway Between Line

To find the number halfway between 40 and 558, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 558 into our formula, we get:

(40 + 558)/2 = 299

Thus, the number halfway between 40 and 558 is 299.

To check that our answer is correct, we subtract 40 from 299 and subtract 299 from 558 and compare the two numbers:

299 - 40 = 259
558 - 299 = 259

As you can see, the halfway number is 259 higher than 40 and 259 lower than 558. Therefore, our halfway between answer of 299 above is correct.
