Halfway Between 99 and 505

When you ask "What number is halfway between 99 and 505?" 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=505.

Halfway Between Line

To find the number halfway between 99 and 505, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 99 and 505 into our formula, we get:

(99 + 505)/2 = 302

Thus, the number halfway between 99 and 505 is 302.

To check that our answer is correct, we subtract 99 from 302 and subtract 302 from 505 and compare the two numbers:

302 - 99 = 203
505 - 302 = 203

As you can see, the halfway number is 203 higher than 99 and 203 lower than 505. Therefore, our halfway between answer of 302 above is correct.
