Halfway Between 85 and 890

When you ask "What number is halfway between 85 and 890?" 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=890.

Halfway Between Line

To find the number halfway between 85 and 890, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 890 into our formula, we get:

(85 + 890)/2 = 487.5

Thus, the number halfway between 85 and 890 is 487.5.

To check that our answer is correct, we subtract 85 from 487.5 and subtract 487.5 from 890 and compare the two numbers:

487.5 - 85 = 402.5
890 - 487.5 = 402.5

As you can see, the halfway number is 402.5 higher than 85 and 402.5 lower than 890. Therefore, our halfway between answer of 487.5 above is correct.
