Halfway Between 10 and 512

When you ask "What number is halfway between 10 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=10 and Y=512.

Halfway Between Line

To find the number halfway between 10 and 512, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 512 into our formula, we get:

(10 + 512)/2 = 261

Thus, the number halfway between 10 and 512 is 261.

To check that our answer is correct, we subtract 10 from 261 and subtract 261 from 512 and compare the two numbers:

261 - 10 = 251
512 - 261 = 251

As you can see, the halfway number is 251 higher than 10 and 251 lower than 512. Therefore, our halfway between answer of 261 above is correct.
