Halfway Between 9 and 500

When you ask "What number is halfway between 9 and 500?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=500.

Halfway Between Line

To find the number halfway between 9 and 500, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 500 into our formula, we get:

(9 + 500)/2 = 254.5

Thus, the number halfway between 9 and 500 is 254.5.

To check that our answer is correct, we subtract 9 from 254.5 and subtract 254.5 from 500 and compare the two numbers:

254.5 - 9 = 245.5
500 - 254.5 = 245.5

As you can see, the halfway number is 245.5 higher than 9 and 245.5 lower than 500. Therefore, our halfway between answer of 254.5 above is correct.
