Halfway Between 23 and 321

When you ask "What number is halfway between 23 and 321?" 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=321.

Halfway Between Line

To find the number halfway between 23 and 321, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 23 and 321 into our formula, we get:

(23 + 321)/2 = 172

Thus, the number halfway between 23 and 321 is 172.

To check that our answer is correct, we subtract 23 from 172 and subtract 172 from 321 and compare the two numbers:

172 - 23 = 149
321 - 172 = 149

As you can see, the halfway number is 149 higher than 23 and 149 lower than 321. Therefore, our halfway between answer of 172 above is correct.
