Halfway Between 80 and 421

When you ask "What number is halfway between 80 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=80 and Y=421.

Halfway Between Line

To find the number halfway between 80 and 421, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 421 into our formula, we get:

(80 + 421)/2 = 250.5

Thus, the number halfway between 80 and 421 is 250.5.

To check that our answer is correct, we subtract 80 from 250.5 and subtract 250.5 from 421 and compare the two numbers:

250.5 - 80 = 170.5
421 - 250.5 = 170.5

As you can see, the halfway number is 170.5 higher than 80 and 170.5 lower than 421. Therefore, our halfway between answer of 250.5 above is correct.
