Halfway Between 55 and 584

When you ask "What number is halfway between 55 and 584?" 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=584.

Halfway Between Line

To find the number halfway between 55 and 584, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 584 into our formula, we get:

(55 + 584)/2 = 319.5

Thus, the number halfway between 55 and 584 is 319.5.

To check that our answer is correct, we subtract 55 from 319.5 and subtract 319.5 from 584 and compare the two numbers:

319.5 - 55 = 264.5
584 - 319.5 = 264.5

As you can see, the halfway number is 264.5 higher than 55 and 264.5 lower than 584. Therefore, our halfway between answer of 319.5 above is correct.
