Halfway Between 4 and 505

When you ask "What number is halfway between 4 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=4 and Y=505.

Halfway Between Line

To find the number halfway between 4 and 505, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 505 into our formula, we get:

(4 + 505)/2 = 254.5

Thus, the number halfway between 4 and 505 is 254.5.

To check that our answer is correct, we subtract 4 from 254.5 and subtract 254.5 from 505 and compare the two numbers:

254.5 - 4 = 250.5
505 - 254.5 = 250.5

As you can see, the halfway number is 250.5 higher than 4 and 250.5 lower than 505. Therefore, our halfway between answer of 254.5 above is correct.
