Halfway Between 40 and 421

When you ask "What number is halfway between 40 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=40 and Y=421.

Halfway Between Line

To find the number halfway between 40 and 421, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 421 into our formula, we get:

(40 + 421)/2 = 230.5

Thus, the number halfway between 40 and 421 is 230.5.

To check that our answer is correct, we subtract 40 from 230.5 and subtract 230.5 from 421 and compare the two numbers:

230.5 - 40 = 190.5
421 - 230.5 = 190.5

As you can see, the halfway number is 190.5 higher than 40 and 190.5 lower than 421. Therefore, our halfway between answer of 230.5 above is correct.
