Halfway Between 15 and 500

When you ask "What number is halfway between 15 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=15 and Y=500.

Halfway Between Line

To find the number halfway between 15 and 500, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 500 into our formula, we get:

(15 + 500)/2 = 257.5

Thus, the number halfway between 15 and 500 is 257.5.

To check that our answer is correct, we subtract 15 from 257.5 and subtract 257.5 from 500 and compare the two numbers:

257.5 - 15 = 242.5
500 - 257.5 = 242.5

As you can see, the halfway number is 242.5 higher than 15 and 242.5 lower than 500. Therefore, our halfway between answer of 257.5 above is correct.
