Halfway Between 78 and 485

When you ask "What number is halfway between 78 and 485?" 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=485.

Halfway Between Line

To find the number halfway between 78 and 485, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 485 into our formula, we get:

(78 + 485)/2 = 281.5

Thus, the number halfway between 78 and 485 is 281.5.

To check that our answer is correct, we subtract 78 from 281.5 and subtract 281.5 from 485 and compare the two numbers:

281.5 - 78 = 203.5
485 - 281.5 = 203.5

As you can see, the halfway number is 203.5 higher than 78 and 203.5 lower than 485. Therefore, our halfway between answer of 281.5 above is correct.
