Halfway Between 20 and 479

When you ask "What number is halfway between 20 and 479?" 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=479.

Halfway Between Line

To find the number halfway between 20 and 479, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 479 into our formula, we get:

(20 + 479)/2 = 249.5

Thus, the number halfway between 20 and 479 is 249.5.

To check that our answer is correct, we subtract 20 from 249.5 and subtract 249.5 from 479 and compare the two numbers:

249.5 - 20 = 229.5
479 - 249.5 = 229.5

As you can see, the halfway number is 229.5 higher than 20 and 229.5 lower than 479. Therefore, our halfway between answer of 249.5 above is correct.
