When you ask "What number is halfway between 100 and 721?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=721.
To find the number halfway between 100 and 721, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 100 and 721 into our formula, we get:
(100 + 721)/2 = 410.5
Thus, the number halfway between 100 and 721 is 410.5.
To check that our answer is correct, we subtract 100 from 410.5 and subtract 410.5 from 721 and compare the two numbers:
410.5 - 100 = 310.5
721 - 410.5 = 310.5
As you can see, the halfway number is 310.5 higher than 100 and 310.5 lower than 721. Therefore, our halfway between answer of 410.5 above is correct.
