Halfway Between 80 and 890

When you ask "What number is halfway between 80 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=80 and Y=890.

Halfway Between Line

To find the number halfway between 80 and 890, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 890 into our formula, we get:

(80 + 890)/2 = 485

Thus, the number halfway between 80 and 890 is 485.

To check that our answer is correct, we subtract 80 from 485 and subtract 485 from 890 and compare the two numbers:

485 - 80 = 405
890 - 485 = 405

As you can see, the halfway number is 405 higher than 80 and 405 lower than 890. Therefore, our halfway between answer of 485 above is correct.
