Halfway Between 100 and 430

When you ask "What number is halfway between 100 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=100 and Y=430.

Halfway Between Line

To find the number halfway between 100 and 430, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 430 into our formula, we get:

(100 + 430)/2 = 265

Thus, the number halfway between 100 and 430 is 265.

To check that our answer is correct, we subtract 100 from 265 and subtract 265 from 430 and compare the two numbers:

265 - 100 = 165
430 - 265 = 165

As you can see, the halfway number is 165 higher than 100 and 165 lower than 430. Therefore, our halfway between answer of 265 above is correct.
