Halfway Between 78 and 585

When you ask "What number is halfway between 78 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=78 and Y=585.

Halfway Between Line

To find the number halfway between 78 and 585, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 585 into our formula, we get:

(78 + 585)/2 = 331.5

Thus, the number halfway between 78 and 585 is 331.5.

To check that our answer is correct, we subtract 78 from 331.5 and subtract 331.5 from 585 and compare the two numbers:

331.5 - 78 = 253.5
585 - 331.5 = 253.5

As you can see, the halfway number is 253.5 higher than 78 and 253.5 lower than 585. Therefore, our halfway between answer of 331.5 above is correct.
