Halfway Between 85 and 778

When you ask "What number is halfway between 85 and 778?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=85 and Y=778.

Halfway Between Line

To find the number halfway between 85 and 778, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 778 into our formula, we get:

(85 + 778)/2 = 431.5

Thus, the number halfway between 85 and 778 is 431.5.

To check that our answer is correct, we subtract 85 from 431.5 and subtract 431.5 from 778 and compare the two numbers:

431.5 - 85 = 346.5
778 - 431.5 = 346.5

As you can see, the halfway number is 346.5 higher than 85 and 346.5 lower than 778. Therefore, our halfway between answer of 431.5 above is correct.
