Halfway Between 57 and 231

When you ask "What number is halfway between 57 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=57 and Y=231.

Halfway Between Line

To find the number halfway between 57 and 231, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 57 and 231 into our formula, we get:

(57 + 231)/2 = 144

Thus, the number halfway between 57 and 231 is 144.

To check that our answer is correct, we subtract 57 from 144 and subtract 144 from 231 and compare the two numbers:

144 - 57 = 87
231 - 144 = 87

As you can see, the halfway number is 87 higher than 57 and 87 lower than 231. Therefore, our halfway between answer of 144 above is correct.
