Halfway Between 85 and 850

When you ask "What number is halfway between 85 and 850?" 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=850.

Halfway Between Line

To find the number halfway between 85 and 850, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 850 into our formula, we get:

(85 + 850)/2 = 467.5

Thus, the number halfway between 85 and 850 is 467.5.

To check that our answer is correct, we subtract 85 from 467.5 and subtract 467.5 from 850 and compare the two numbers:

467.5 - 85 = 382.5
850 - 467.5 = 382.5

As you can see, the halfway number is 382.5 higher than 85 and 382.5 lower than 850. Therefore, our halfway between answer of 467.5 above is correct.
