Halfway Between 99 and 500

When you ask "What number is halfway between 99 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=99 and Y=500.

Halfway Between Line

To find the number halfway between 99 and 500, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 99 and 500 into our formula, we get:

(99 + 500)/2 = 299.5

Thus, the number halfway between 99 and 500 is 299.5.

To check that our answer is correct, we subtract 99 from 299.5 and subtract 299.5 from 500 and compare the two numbers:

299.5 - 99 = 200.5
500 - 299.5 = 200.5

As you can see, the halfway number is 200.5 higher than 99 and 200.5 lower than 500. Therefore, our halfway between answer of 299.5 above is correct.
