Halfway Between 23 and 257

When you ask "What number is halfway between 23 and 257?" 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=257.

Halfway Between Line

To find the number halfway between 23 and 257, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 23 and 257 into our formula, we get:

(23 + 257)/2 = 140

Thus, the number halfway between 23 and 257 is 140.

To check that our answer is correct, we subtract 23 from 140 and subtract 140 from 257 and compare the two numbers:

140 - 23 = 117
257 - 140 = 117

As you can see, the halfway number is 117 higher than 23 and 117 lower than 257. Therefore, our halfway between answer of 140 above is correct.
