When you ask "What number is halfway between 81 and 190?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=81 and Y=190.
To find the number halfway between 81 and 190, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 81 and 190 into our formula, we get:
(81 + 190)/2 = 135.5
Thus, the number halfway between 81 and 190 is 135.5.
To check that our answer is correct, we subtract 81 from 135.5 and subtract 135.5 from 190 and compare the two numbers:
135.5 - 81 = 54.5
190 - 135.5 = 54.5
As you can see, the halfway number is 54.5 higher than 81 and 54.5 lower than 190. Therefore, our halfway between answer of 135.5 above is correct.
