Halfway Between 9 and 331

When you ask "What number is halfway between 9 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=9 and Y=331.

Halfway Between Line

To find the number halfway between 9 and 331, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 331 into our formula, we get:

(9 + 331)/2 = 170

Thus, the number halfway between 9 and 331 is 170.

To check that our answer is correct, we subtract 9 from 170 and subtract 170 from 331 and compare the two numbers:

170 - 9 = 161
331 - 170 = 161

As you can see, the halfway number is 161 higher than 9 and 161 lower than 331. Therefore, our halfway between answer of 170 above is correct.
