Halfway Between 45 and 511

When you ask "What number is halfway between 45 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=45 and Y=511.

Halfway Between Line

To find the number halfway between 45 and 511, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 511 into our formula, we get:

(45 + 511)/2 = 278

Thus, the number halfway between 45 and 511 is 278.

To check that our answer is correct, we subtract 45 from 278 and subtract 278 from 511 and compare the two numbers:

278 - 45 = 233
511 - 278 = 233

As you can see, the halfway number is 233 higher than 45 and 233 lower than 511. Therefore, our halfway between answer of 278 above is correct.
