Halfway Between 80 and 430

When you ask "What number is halfway between 80 and 430?" 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=430.

Halfway Between Line

To find the number halfway between 80 and 430, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 430 into our formula, we get:

(80 + 430)/2 = 255

Thus, the number halfway between 80 and 430 is 255.

To check that our answer is correct, we subtract 80 from 255 and subtract 255 from 430 and compare the two numbers:

255 - 80 = 175
430 - 255 = 175

As you can see, the halfway number is 175 higher than 80 and 175 lower than 430. Therefore, our halfway between answer of 255 above is correct.
