Halfway Between 40 and 218

When you ask "What number is halfway between 40 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=40 and Y=218.

Halfway Between Line

To find the number halfway between 40 and 218, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 218 into our formula, we get:

(40 + 218)/2 = 129

Thus, the number halfway between 40 and 218 is 129.

To check that our answer is correct, we subtract 40 from 129 and subtract 129 from 218 and compare the two numbers:

129 - 40 = 89
218 - 129 = 89

As you can see, the halfway number is 89 higher than 40 and 89 lower than 218. Therefore, our halfway between answer of 129 above is correct.
