Halfway Between 23 and 278

When you ask "What number is halfway between 23 and 278?" 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=278.

Halfway Between Line

To find the number halfway between 23 and 278, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 23 and 278 into our formula, we get:

(23 + 278)/2 = 150.5

Thus, the number halfway between 23 and 278 is 150.5.

To check that our answer is correct, we subtract 23 from 150.5 and subtract 150.5 from 278 and compare the two numbers:

150.5 - 23 = 127.5
278 - 150.5 = 127.5

As you can see, the halfway number is 127.5 higher than 23 and 127.5 lower than 278. Therefore, our halfway between answer of 150.5 above is correct.
