Halfway Between 63 and 423

When you ask "What number is halfway between 63 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=63 and Y=423.

Halfway Between Line

To find the number halfway between 63 and 423, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 63 and 423 into our formula, we get:

(63 + 423)/2 = 243

Thus, the number halfway between 63 and 423 is 243.

To check that our answer is correct, we subtract 63 from 243 and subtract 243 from 423 and compare the two numbers:

243 - 63 = 180
423 - 243 = 180

As you can see, the halfway number is 180 higher than 63 and 180 lower than 423. Therefore, our halfway between answer of 243 above is correct.
