Halfway Between 20 and 499

When you ask "What number is halfway between 20 and 499?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=499.

Halfway Between Line

To find the number halfway between 20 and 499, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 499 into our formula, we get:

(20 + 499)/2 = 259.5

Thus, the number halfway between 20 and 499 is 259.5.

To check that our answer is correct, we subtract 20 from 259.5 and subtract 259.5 from 499 and compare the two numbers:

259.5 - 20 = 239.5
499 - 259.5 = 239.5

As you can see, the halfway number is 239.5 higher than 20 and 239.5 lower than 499. Therefore, our halfway between answer of 259.5 above is correct.
