When you ask "What number is halfway between 10 and 989?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=10 and Y=989.
To find the number halfway between 10 and 989, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 10 and 989 into our formula, we get:
(10 + 989)/2 = 499.5
Thus, the number halfway between 10 and 989 is 499.5.
To check that our answer is correct, we subtract 10 from 499.5 and subtract 499.5 from 989 and compare the two numbers:
499.5 - 10 = 489.5
989 - 499.5 = 489.5
As you can see, the halfway number is 489.5 higher than 10 and 489.5 lower than 989. Therefore, our halfway between answer of 499.5 above is correct.
