Halfway Between 85 and 650

When you ask "What number is halfway between 85 and 650?" 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=650.

Halfway Between Line

To find the number halfway between 85 and 650, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 650 into our formula, we get:

(85 + 650)/2 = 367.5

Thus, the number halfway between 85 and 650 is 367.5.

To check that our answer is correct, we subtract 85 from 367.5 and subtract 367.5 from 650 and compare the two numbers:

367.5 - 85 = 282.5
650 - 367.5 = 282.5

As you can see, the halfway number is 282.5 higher than 85 and 282.5 lower than 650. Therefore, our halfway between answer of 367.5 above is correct.
