Halfway Between 15 and 501

When you ask "What number is halfway between 15 and 501?" 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=501.

Halfway Between Line

To find the number halfway between 15 and 501, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 501 into our formula, we get:

(15 + 501)/2 = 258

Thus, the number halfway between 15 and 501 is 258.

To check that our answer is correct, we subtract 15 from 258 and subtract 258 from 501 and compare the two numbers:

258 - 15 = 243
501 - 258 = 243

As you can see, the halfway number is 243 higher than 15 and 243 lower than 501. Therefore, our halfway between answer of 258 above is correct.
