Halfway Between 13 and 231

When you ask "What number is halfway between 13 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=13 and Y=231.

Halfway Between Line

To find the number halfway between 13 and 231, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 231 into our formula, we get:

(13 + 231)/2 = 122

Thus, the number halfway between 13 and 231 is 122.

To check that our answer is correct, we subtract 13 from 122 and subtract 122 from 231 and compare the two numbers:

122 - 13 = 109
231 - 122 = 109

As you can see, the halfway number is 109 higher than 13 and 109 lower than 231. Therefore, our halfway between answer of 122 above is correct.
