Halfway Between 67 and 511

When you ask "What number is halfway between 67 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=67 and Y=511.

Halfway Between Line

To find the number halfway between 67 and 511, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 67 and 511 into our formula, we get:

(67 + 511)/2 = 289

Thus, the number halfway between 67 and 511 is 289.

To check that our answer is correct, we subtract 67 from 289 and subtract 289 from 511 and compare the two numbers:

289 - 67 = 222
511 - 289 = 222

As you can see, the halfway number is 222 higher than 67 and 222 lower than 511. Therefore, our halfway between answer of 289 above is correct.
