When you ask "What number is halfway between 97 and 543?" 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=543.

To find the number halfway between 97 and 543, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 97 and 543 into our formula, we get:
(97 + 543)/2 = 320
Thus, the number halfway between 97 and 543 is 320.
To check that our answer is correct, we subtract 97 from 320 and subtract 320 from 543 and compare the two numbers:
320 - 97 = 223
543 - 320 = 223
As you can see, the halfway number is 223 higher than 97 and 223 lower than 543. Therefore, our halfway between answer of 320 above is correct.
