Halfway Between 4 and 506

When you ask "What number is halfway between 4 and 506?" 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=506.

Halfway Between Line

To find the number halfway between 4 and 506, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 506 into our formula, we get:

(4 + 506)/2 = 255

Thus, the number halfway between 4 and 506 is 255.

To check that our answer is correct, we subtract 4 from 255 and subtract 255 from 506 and compare the two numbers:

255 - 4 = 251
506 - 255 = 251

As you can see, the halfway number is 251 higher than 4 and 251 lower than 506. Therefore, our halfway between answer of 255 above is correct.
