Halfway Between 65 and 512

When you ask "What number is halfway between 65 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=65 and Y=512.

Halfway Between Line

To find the number halfway between 65 and 512, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 512 into our formula, we get:

(65 + 512)/2 = 288.5

Thus, the number halfway between 65 and 512 is 288.5.

To check that our answer is correct, we subtract 65 from 288.5 and subtract 288.5 from 512 and compare the two numbers:

288.5 - 65 = 223.5
512 - 288.5 = 223.5

As you can see, the halfway number is 223.5 higher than 65 and 223.5 lower than 512. Therefore, our halfway between answer of 288.5 above is correct.
