Halfway Between 90 and 308

When you ask "What number is halfway between 90 and 308?" 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=308.

Halfway Between Line

To find the number halfway between 90 and 308, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 308 into our formula, we get:

(90 + 308)/2 = 199

Thus, the number halfway between 90 and 308 is 199.

To check that our answer is correct, we subtract 90 from 199 and subtract 199 from 308 and compare the two numbers:

199 - 90 = 109
308 - 199 = 109

As you can see, the halfway number is 109 higher than 90 and 109 lower than 308. Therefore, our halfway between answer of 199 above is correct.
