Halfway Between 90 and 310

When you ask "What number is halfway between 90 and 310?" 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=310.

Halfway Between Line

To find the number halfway between 90 and 310, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 310 into our formula, we get:

(90 + 310)/2 = 200

Thus, the number halfway between 90 and 310 is 200.

To check that our answer is correct, we subtract 90 from 200 and subtract 200 from 310 and compare the two numbers:

200 - 90 = 110
310 - 200 = 110

As you can see, the halfway number is 110 higher than 90 and 110 lower than 310. Therefore, our halfway between answer of 200 above is correct.
