Halfway Between 85 and 858




When you ask "What number is halfway between 85 and 858?" 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=858.



To find the number halfway between 85 and 858, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 858 into our formula, we get:

(85 + 858)/2 = 471.5

Thus, the number halfway between 85 and 858 is 471.5.


To check that our answer is correct, we subtract 85 from 471.5 and subtract 471.5 from 858 and compare the two numbers:

471.5 - 85 = 386.5
858 - 471.5 = 386.5

As you can see, the halfway number is 386.5 higher than 85 and 386.5 lower than 858. Therefore, our halfway between answer of 471.5 above is correct.
