Halfway Between 23 and 251

When you ask "What number is halfway between 23 and 251?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=23 and Y=251.

Halfway Between Line

To find the number halfway between 23 and 251, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 23 and 251 into our formula, we get:

(23 + 251)/2 = 137

Thus, the number halfway between 23 and 251 is 137.

To check that our answer is correct, we subtract 23 from 137 and subtract 137 from 251 and compare the two numbers:

137 - 23 = 114
251 - 137 = 114

As you can see, the halfway number is 114 higher than 23 and 114 lower than 251. Therefore, our halfway between answer of 137 above is correct.
