Halfway Between 90 and 331

When you ask "What number is halfway between 90 and 331?" 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=331.

Halfway Between Line

To find the number halfway between 90 and 331, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 331 into our formula, we get:

(90 + 331)/2 = 210.5

Thus, the number halfway between 90 and 331 is 210.5.

To check that our answer is correct, we subtract 90 from 210.5 and subtract 210.5 from 331 and compare the two numbers:

210.5 - 90 = 120.5
331 - 210.5 = 120.5

As you can see, the halfway number is 120.5 higher than 90 and 120.5 lower than 331. Therefore, our halfway between answer of 210.5 above is correct.
