Halfway Between 5 and 555

When you ask "What number is halfway between 5 and 555?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=5 and Y=555.

Halfway Between Line

To find the number halfway between 5 and 555, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 555 into our formula, we get:

(5 + 555)/2 = 280

Thus, the number halfway between 5 and 555 is 280.

To check that our answer is correct, we subtract 5 from 280 and subtract 280 from 555 and compare the two numbers:

280 - 5 = 275
555 - 280 = 275

As you can see, the halfway number is 275 higher than 5 and 275 lower than 555. Therefore, our halfway between answer of 280 above is correct.
