Halfway Between 90 and 218

When you ask "What number is halfway between 90 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=90 and Y=218.

Halfway Between Line

To find the number halfway between 90 and 218, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 218 into our formula, we get:

(90 + 218)/2 = 154

Thus, the number halfway between 90 and 218 is 154.

To check that our answer is correct, we subtract 90 from 154 and subtract 154 from 218 and compare the two numbers:

154 - 90 = 64
218 - 154 = 64

As you can see, the halfway number is 64 higher than 90 and 64 lower than 218. Therefore, our halfway between answer of 154 above is correct.
