Halfway Between 21 and 525

When you ask "What number is halfway between 21 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=21 and Y=525.

Halfway Between Line

To find the number halfway between 21 and 525, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 525 into our formula, we get:

(21 + 525)/2 = 273

Thus, the number halfway between 21 and 525 is 273.

To check that our answer is correct, we subtract 21 from 273 and subtract 273 from 525 and compare the two numbers:

273 - 21 = 252
525 - 273 = 252

As you can see, the halfway number is 252 higher than 21 and 252 lower than 525. Therefore, our halfway between answer of 273 above is correct.
