Halfway Between 17 and 530

When you ask "What number is halfway between 17 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=17 and Y=530.

Halfway Between Line

To find the number halfway between 17 and 530, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 530 into our formula, we get:

(17 + 530)/2 = 273.5

Thus, the number halfway between 17 and 530 is 273.5.

To check that our answer is correct, we subtract 17 from 273.5 and subtract 273.5 from 530 and compare the two numbers:

273.5 - 17 = 256.5
530 - 273.5 = 256.5

As you can see, the halfway number is 256.5 higher than 17 and 256.5 lower than 530. Therefore, our halfway between answer of 273.5 above is correct.
