Halfway Between 10 and 499

When you ask "What number is halfway between 10 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=10 and Y=499.

Halfway Between Line

To find the number halfway between 10 and 499, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 499 into our formula, we get:

(10 + 499)/2 = 254.5

Thus, the number halfway between 10 and 499 is 254.5.

To check that our answer is correct, we subtract 10 from 254.5 and subtract 254.5 from 499 and compare the two numbers:

254.5 - 10 = 244.5
499 - 254.5 = 244.5

As you can see, the halfway number is 244.5 higher than 10 and 244.5 lower than 499. Therefore, our halfway between answer of 254.5 above is correct.
