Halfway Between 89 and 490

When you ask "What number is halfway between 89 and 490?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=89 and Y=490.

Halfway Between Line

To find the number halfway between 89 and 490, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 490 into our formula, we get:

(89 + 490)/2 = 289.5

Thus, the number halfway between 89 and 490 is 289.5.

To check that our answer is correct, we subtract 89 from 289.5 and subtract 289.5 from 490 and compare the two numbers:

289.5 - 89 = 200.5
490 - 289.5 = 200.5

As you can see, the halfway number is 200.5 higher than 89 and 200.5 lower than 490. Therefore, our halfway between answer of 289.5 above is correct.
