Halfway Between 55 and 563

When you ask "What number is halfway between 55 and 563?" 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=563.

Halfway Between Line

To find the number halfway between 55 and 563, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 563 into our formula, we get:

(55 + 563)/2 = 309

Thus, the number halfway between 55 and 563 is 309.

To check that our answer is correct, we subtract 55 from 309 and subtract 309 from 563 and compare the two numbers:

309 - 55 = 254
563 - 309 = 254

As you can see, the halfway number is 254 higher than 55 and 254 lower than 563. Therefore, our halfway between answer of 309 above is correct.
