Halfway Between 78 and 430

When you ask "What number is halfway between 78 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=78 and Y=430.

Halfway Between Line

To find the number halfway between 78 and 430, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 430 into our formula, we get:

(78 + 430)/2 = 254

Thus, the number halfway between 78 and 430 is 254.

To check that our answer is correct, we subtract 78 from 254 and subtract 254 from 430 and compare the two numbers:

254 - 78 = 176
430 - 254 = 176

As you can see, the halfway number is 176 higher than 78 and 176 lower than 430. Therefore, our halfway between answer of 254 above is correct.
