Halfway Between 75 and 421

When you ask "What number is halfway between 75 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=75 and Y=421.

Halfway Between Line

To find the number halfway between 75 and 421, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 75 and 421 into our formula, we get:

(75 + 421)/2 = 248

Thus, the number halfway between 75 and 421 is 248.

To check that our answer is correct, we subtract 75 from 248 and subtract 248 from 421 and compare the two numbers:

248 - 75 = 173
421 - 248 = 173

As you can see, the halfway number is 173 higher than 75 and 173 lower than 421. Therefore, our halfway between answer of 248 above is correct.
