Halfway Between 50 and 511

When you ask "What number is halfway between 50 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=50 and Y=511.

Halfway Between Line

To find the number halfway between 50 and 511, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 50 and 511 into our formula, we get:

(50 + 511)/2 = 280.5

Thus, the number halfway between 50 and 511 is 280.5.

To check that our answer is correct, we subtract 50 from 280.5 and subtract 280.5 from 511 and compare the two numbers:

280.5 - 50 = 230.5
511 - 280.5 = 230.5

As you can see, the halfway number is 230.5 higher than 50 and 230.5 lower than 511. Therefore, our halfway between answer of 280.5 above is correct.
