Halfway Between 17 and 512

When you ask "What number is halfway between 17 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=17 and Y=512.

Halfway Between Line

To find the number halfway between 17 and 512, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 512 into our formula, we get:

(17 + 512)/2 = 264.5

Thus, the number halfway between 17 and 512 is 264.5.

To check that our answer is correct, we subtract 17 from 264.5 and subtract 264.5 from 512 and compare the two numbers:

264.5 - 17 = 247.5
512 - 264.5 = 247.5

As you can see, the halfway number is 247.5 higher than 17 and 247.5 lower than 512. Therefore, our halfway between answer of 264.5 above is correct.
