When you ask "What number is halfway between 18 and 891?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=18 and Y=891.
To find the number halfway between 18 and 891, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 18 and 891 into our formula, we get:
(18 + 891)/2 = 454.5
Thus, the number halfway between 18 and 891 is 454.5.
To check that our answer is correct, we subtract 18 from 454.5 and subtract 454.5 from 891 and compare the two numbers:
454.5 - 18 = 436.5
891 - 454.5 = 436.5
As you can see, the halfway number is 436.5 higher than 18 and 436.5 lower than 891. Therefore, our halfway between answer of 454.5 above is correct.
