Halfway Between 85 and 842

When you ask "What number is halfway between 85 and 842?" 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=842.

Halfway Between Line

To find the number halfway between 85 and 842, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 842 into our formula, we get:

(85 + 842)/2 = 463.5

Thus, the number halfway between 85 and 842 is 463.5.

To check that our answer is correct, we subtract 85 from 463.5 and subtract 463.5 from 842 and compare the two numbers:

463.5 - 85 = 378.5
842 - 463.5 = 378.5

As you can see, the halfway number is 378.5 higher than 85 and 378.5 lower than 842. Therefore, our halfway between answer of 463.5 above is correct.
