Halfway Between 18 and 500

When you ask "What number is halfway between 18 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=18 and Y=500.

Halfway Between Line

To find the number halfway between 18 and 500, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 18 and 500 into our formula, we get:

(18 + 500)/2 = 259

Thus, the number halfway between 18 and 500 is 259.

To check that our answer is correct, we subtract 18 from 259 and subtract 259 from 500 and compare the two numbers:

259 - 18 = 241
500 - 259 = 241

As you can see, the halfway number is 241 higher than 18 and 241 lower than 500. Therefore, our halfway between answer of 259 above is correct.
