Halfway Between 30 and 512

When you ask "What number is halfway between 30 and 512?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=30 and Y=512.

Halfway Between Line

To find the number halfway between 30 and 512, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 512 into our formula, we get:

(30 + 512)/2 = 271

Thus, the number halfway between 30 and 512 is 271.

To check that our answer is correct, we subtract 30 from 271 and subtract 271 from 512 and compare the two numbers:

271 - 30 = 241
512 - 271 = 241

As you can see, the halfway number is 241 higher than 30 and 241 lower than 512. Therefore, our halfway between answer of 271 above is correct.
