Halfway Between 81 and 331

When you ask "What number is halfway between 81 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=81 and Y=331.

Halfway Between Line

To find the number halfway between 81 and 331, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 81 and 331 into our formula, we get:

(81 + 331)/2 = 206

Thus, the number halfway between 81 and 331 is 206.

To check that our answer is correct, we subtract 81 from 206 and subtract 206 from 331 and compare the two numbers:

206 - 81 = 125
331 - 206 = 125

As you can see, the halfway number is 125 higher than 81 and 125 lower than 331. Therefore, our halfway between answer of 206 above is correct.
