Halfway Between 15 and 507

When you ask "What number is halfway between 15 and 507?" 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=507.

Halfway Between Line

To find the number halfway between 15 and 507, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 507 into our formula, we get:

(15 + 507)/2 = 261

Thus, the number halfway between 15 and 507 is 261.

To check that our answer is correct, we subtract 15 from 261 and subtract 261 from 507 and compare the two numbers:

261 - 15 = 246
507 - 261 = 246

As you can see, the halfway number is 246 higher than 15 and 246 lower than 507. Therefore, our halfway between answer of 261 above is correct.
