Halfway Between 80 and 851

When you ask "What number is halfway between 80 and 851?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=851.

Halfway Between Line

To find the number halfway between 80 and 851, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 851 into our formula, we get:

(80 + 851)/2 = 465.5

Thus, the number halfway between 80 and 851 is 465.5.

To check that our answer is correct, we subtract 80 from 465.5 and subtract 465.5 from 851 and compare the two numbers:

465.5 - 80 = 385.5
851 - 465.5 = 385.5

As you can see, the halfway number is 385.5 higher than 80 and 385.5 lower than 851. Therefore, our halfway between answer of 465.5 above is correct.
