When you ask "What number is halfway between 20 and 218?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=218.
To find the number halfway between 20 and 218, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 20 and 218 into our formula, we get:
(20 + 218)/2 = 119
Thus, the number halfway between 20 and 218 is 119.
To check that our answer is correct, we subtract 20 from 119 and subtract 119 from 218 and compare the two numbers:
119 - 20 = 99
218 - 119 = 99
As you can see, the halfway number is 99 higher than 20 and 99 lower than 218. Therefore, our halfway between answer of 119 above is correct.
