Halfway Between 45 and 421

When you ask "What number is halfway between 45 and 421?" 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=421.

Halfway Between Line

To find the number halfway between 45 and 421, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 421 into our formula, we get:

(45 + 421)/2 = 233

Thus, the number halfway between 45 and 421 is 233.

To check that our answer is correct, we subtract 45 from 233 and subtract 233 from 421 and compare the two numbers:

233 - 45 = 188
421 - 233 = 188

As you can see, the halfway number is 188 higher than 45 and 188 lower than 421. Therefore, our halfway between answer of 233 above is correct.
