When you ask "What number is halfway between 3 and 281?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=3 and Y=281.
To find the number halfway between 3 and 281, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 3 and 281 into our formula, we get:
(3 + 281)/2 = 142
Thus, the number halfway between 3 and 281 is 142.
To check that our answer is correct, we subtract 3 from 142 and subtract 142 from 281 and compare the two numbers:
142 - 3 = 139
281 - 142 = 139
As you can see, the halfway number is 139 higher than 3 and 139 lower than 281. Therefore, our halfway between answer of 142 above is correct.
