Halfway Between 15 and 525

When you ask "What number is halfway between 15 and 525?" 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=525.

Halfway Between Line

To find the number halfway between 15 and 525, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 525 into our formula, we get:

(15 + 525)/2 = 270

Thus, the number halfway between 15 and 525 is 270.

To check that our answer is correct, we subtract 15 from 270 and subtract 270 from 525 and compare the two numbers:

270 - 15 = 255
525 - 270 = 255

As you can see, the halfway number is 255 higher than 15 and 255 lower than 525. Therefore, our halfway between answer of 270 above is correct.
