Halfway Between 65 and 511

When you ask "What number is halfway between 65 and 511?" 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=511.

Halfway Between Line

To find the number halfway between 65 and 511, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 511 into our formula, we get:

(65 + 511)/2 = 288

Thus, the number halfway between 65 and 511 is 288.

To check that our answer is correct, we subtract 65 from 288 and subtract 288 from 511 and compare the two numbers:

288 - 65 = 223
511 - 288 = 223

As you can see, the halfway number is 223 higher than 65 and 223 lower than 511. Therefore, our halfway between answer of 288 above is correct.
