Halfway Between 55 and 506

When you ask "What number is halfway between 55 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=55 and Y=506.

Halfway Between Line

To find the number halfway between 55 and 506, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 506 into our formula, we get:

(55 + 506)/2 = 280.5

Thus, the number halfway between 55 and 506 is 280.5.

To check that our answer is correct, we subtract 55 from 280.5 and subtract 280.5 from 506 and compare the two numbers:

280.5 - 55 = 225.5
506 - 280.5 = 225.5

As you can see, the halfway number is 225.5 higher than 55 and 225.5 lower than 506. Therefore, our halfway between answer of 280.5 above is correct.
