Halfway Between 81 and 337

When you ask "What number is halfway between 81 and 337?" 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=337.

Halfway Between Line

To find the number halfway between 81 and 337, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 81 and 337 into our formula, we get:

(81 + 337)/2 = 209

Thus, the number halfway between 81 and 337 is 209.

To check that our answer is correct, we subtract 81 from 209 and subtract 209 from 337 and compare the two numbers:

209 - 81 = 128
337 - 209 = 128

As you can see, the halfway number is 128 higher than 81 and 128 lower than 337. Therefore, our halfway between answer of 209 above is correct.
