Halfway Between 90 and 890

When you ask "What number is halfway between 90 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=90 and Y=890.

Halfway Between Line

To find the number halfway between 90 and 890, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 890 into our formula, we get:

(90 + 890)/2 = 490

Thus, the number halfway between 90 and 890 is 490.

To check that our answer is correct, we subtract 90 from 490 and subtract 490 from 890 and compare the two numbers:

490 - 90 = 400
890 - 490 = 400

As you can see, the halfway number is 400 higher than 90 and 400 lower than 890. Therefore, our halfway between answer of 490 above is correct.
