Halfway Between 20 and 530

When you ask "What number is halfway between 20 and 530?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=530.

Halfway Between Line

To find the number halfway between 20 and 530, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 530 into our formula, we get:

(20 + 530)/2 = 275

Thus, the number halfway between 20 and 530 is 275.

To check that our answer is correct, we subtract 20 from 275 and subtract 275 from 530 and compare the two numbers:

275 - 20 = 255
530 - 275 = 255

As you can see, the halfway number is 255 higher than 20 and 255 lower than 530. Therefore, our halfway between answer of 275 above is correct.
