Halfway Between 45 and 423

When you ask "What number is halfway between 45 and 423?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=45 and Y=423.

Halfway Between Line

To find the number halfway between 45 and 423, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 423 into our formula, we get:

(45 + 423)/2 = 234

Thus, the number halfway between 45 and 423 is 234.

To check that our answer is correct, we subtract 45 from 234 and subtract 234 from 423 and compare the two numbers:

234 - 45 = 189
423 - 234 = 189

As you can see, the halfway number is 189 higher than 45 and 189 lower than 423. Therefore, our halfway between answer of 234 above is correct.
