Halfway Between 40 and 505

When you ask "What number is halfway between 40 and 505?" 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=505.

Halfway Between Line

To find the number halfway between 40 and 505, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 505 into our formula, we get:

(40 + 505)/2 = 272.5

Thus, the number halfway between 40 and 505 is 272.5.

To check that our answer is correct, we subtract 40 from 272.5 and subtract 272.5 from 505 and compare the two numbers:

272.5 - 40 = 232.5
505 - 272.5 = 232.5

As you can see, the halfway number is 232.5 higher than 40 and 232.5 lower than 505. Therefore, our halfway between answer of 272.5 above is correct.
