When you ask "What number is halfway between 3 and 17?" 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=17.
To find the number halfway between 3 and 17, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 3 and 17 into our formula, we get:
(3 + 17)/2 = 10
Thus, the number halfway between 3 and 17 is 10.
To check that our answer is correct, we subtract 3 from 10 and subtract 10 from 17 and compare the two numbers:
10 - 3 = 7
17 - 10 = 7
As you can see, the halfway number is 7 higher than 3 and 7 lower than 17. Therefore, our halfway between answer of 10 above is correct.
