Halfway Between 100 and 530

When you ask "What number is halfway between 100 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=100 and Y=530.

Halfway Between Line

To find the number halfway between 100 and 530, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 530 into our formula, we get:

(100 + 530)/2 = 315

Thus, the number halfway between 100 and 530 is 315.

To check that our answer is correct, we subtract 100 from 315 and subtract 315 from 530 and compare the two numbers:

315 - 100 = 215
530 - 315 = 215

As you can see, the halfway number is 215 higher than 100 and 215 lower than 530. Therefore, our halfway between answer of 315 above is correct.
