When you ask "What number is halfway between 18 and 529?" 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=529.
To find the number halfway between 18 and 529, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 18 and 529 into our formula, we get:
(18 + 529)/2 = 273.5
Thus, the number halfway between 18 and 529 is 273.5.
To check that our answer is correct, we subtract 18 from 273.5 and subtract 273.5 from 529 and compare the two numbers:
273.5 - 18 = 255.5
529 - 273.5 = 255.5
As you can see, the halfway number is 255.5 higher than 18 and 255.5 lower than 529. Therefore, our halfway between answer of 273.5 above is correct.
