Halfway Between 11 and 231

When you ask "What number is halfway between 11 and 231?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=11 and Y=231.

Halfway Between Line

To find the number halfway between 11 and 231, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 231 into our formula, we get:

(11 + 231)/2 = 121

Thus, the number halfway between 11 and 231 is 121.

To check that our answer is correct, we subtract 11 from 121 and subtract 121 from 231 and compare the two numbers:

121 - 11 = 110
231 - 121 = 110

As you can see, the halfway number is 110 higher than 11 and 110 lower than 231. Therefore, our halfway between answer of 121 above is correct.
