Halfway Between 9 and 502

When you ask "What number is halfway between 9 and 502?" 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=502.

Halfway Between Line

To find the number halfway between 9 and 502, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 502 into our formula, we get:

(9 + 502)/2 = 255.5

Thus, the number halfway between 9 and 502 is 255.5.

To check that our answer is correct, we subtract 9 from 255.5 and subtract 255.5 from 502 and compare the two numbers:

255.5 - 9 = 246.5
502 - 255.5 = 246.5

As you can see, the halfway number is 246.5 higher than 9 and 246.5 lower than 502. Therefore, our halfway between answer of 255.5 above is correct.
