When you ask "What number is halfway between 97 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=97 and Y=721.
To find the number halfway between 97 and 721, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 97 and 721 into our formula, we get:
(97 + 721)/2 = 409
Thus, the number halfway between 97 and 721 is 409.
To check that our answer is correct, we subtract 97 from 409 and subtract 409 from 721 and compare the two numbers:
409 - 97 = 312
721 - 409 = 312
As you can see, the halfway number is 312 higher than 97 and 312 lower than 721. Therefore, our halfway between answer of 409 above is correct.
