Halfway Between 90 and 318

When you ask "What number is halfway between 90 and 318?" 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=318.

Halfway Between Line

To find the number halfway between 90 and 318, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 318 into our formula, we get:

(90 + 318)/2 = 204

Thus, the number halfway between 90 and 318 is 204.

To check that our answer is correct, we subtract 90 from 204 and subtract 204 from 318 and compare the two numbers:

204 - 90 = 114
318 - 204 = 114

As you can see, the halfway number is 114 higher than 90 and 114 lower than 318. Therefore, our halfway between answer of 204 above is correct.
