Halfway Between 84 and 428

When you ask "What number is halfway between 84 and 428?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=84 and Y=428.

Halfway Between Line

To find the number halfway between 84 and 428, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 84 and 428 into our formula, we get:

(84 + 428)/2 = 256

Thus, the number halfway between 84 and 428 is 256.

To check that our answer is correct, we subtract 84 from 256 and subtract 256 from 428 and compare the two numbers:

256 - 84 = 172
428 - 256 = 172

As you can see, the halfway number is 172 higher than 84 and 172 lower than 428. Therefore, our halfway between answer of 256 above is correct.
