Halfway Between 80 and 423

When you ask "What number is halfway between 80 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=80 and Y=423.

Halfway Between Line

To find the number halfway between 80 and 423, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 423 into our formula, we get:

(80 + 423)/2 = 251.5

Thus, the number halfway between 80 and 423 is 251.5.

To check that our answer is correct, we subtract 80 from 251.5 and subtract 251.5 from 423 and compare the two numbers:

251.5 - 80 = 171.5
423 - 251.5 = 171.5

As you can see, the halfway number is 171.5 higher than 80 and 171.5 lower than 423. Therefore, our halfway between answer of 251.5 above is correct.
