Halfway Between 4 and 517

When you ask "What number is halfway between 4 and 517?" 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=517.

Halfway Between Line

To find the number halfway between 4 and 517, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 517 into our formula, we get:

(4 + 517)/2 = 260.5

Thus, the number halfway between 4 and 517 is 260.5.

To check that our answer is correct, we subtract 4 from 260.5 and subtract 260.5 from 517 and compare the two numbers:

260.5 - 4 = 256.5
517 - 260.5 = 256.5

As you can see, the halfway number is 256.5 higher than 4 and 256.5 lower than 517. Therefore, our halfway between answer of 260.5 above is correct.
