Halfway Between 40 and 511

When you ask "What number is halfway between 40 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=40 and Y=511.

Halfway Between Line

To find the number halfway between 40 and 511, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 511 into our formula, we get:

(40 + 511)/2 = 275.5

Thus, the number halfway between 40 and 511 is 275.5.

To check that our answer is correct, we subtract 40 from 275.5 and subtract 275.5 from 511 and compare the two numbers:

275.5 - 40 = 235.5
511 - 275.5 = 235.5

As you can see, the halfway number is 235.5 higher than 40 and 235.5 lower than 511. Therefore, our halfway between answer of 275.5 above is correct.
