Halfway Between 55 and 585

When you ask "What number is halfway between 55 and 585?" 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=585.

Halfway Between Line

To find the number halfway between 55 and 585, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 585 into our formula, we get:

(55 + 585)/2 = 320

Thus, the number halfway between 55 and 585 is 320.

To check that our answer is correct, we subtract 55 from 320 and subtract 320 from 585 and compare the two numbers:

320 - 55 = 265
585 - 320 = 265

As you can see, the halfway number is 265 higher than 55 and 265 lower than 585. Therefore, our halfway between answer of 320 above is correct.
