When you ask "What number is halfway between 19 and 81?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=19 and Y=81.
To find the number halfway between 19 and 81, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 19 and 81 into our formula, we get:
(19 + 81)/2 = 50
Thus, the number halfway between 19 and 81 is 50.
To check that our answer is correct, we subtract 19 from 50 and subtract 50 from 81 and compare the two numbers:
50 - 19 = 31
81 - 50 = 31
As you can see, the halfway number is 31 higher than 19 and 31 lower than 81. Therefore, our halfway between answer of 50 above is correct.
