When you ask "What number is halfway between 3 and 38?" 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=38.
To find the number halfway between 3 and 38, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 3 and 38 into our formula, we get:
(3 + 38)/2 = 20.5
Thus, the number halfway between 3 and 38 is 20.5.
To check that our answer is correct, we subtract 3 from 20.5 and subtract 20.5 from 38 and compare the two numbers:
20.5 - 3 = 17.5
38 - 20.5 = 17.5
As you can see, the halfway number is 17.5 higher than 3 and 17.5 lower than 38. Therefore, our halfway between answer of 20.5 above is correct.
