Halfway Between 30 and 428

When you ask "What number is halfway between 30 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=30 and Y=428.

Halfway Between Line

To find the number halfway between 30 and 428, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 428 into our formula, we get:

(30 + 428)/2 = 229

Thus, the number halfway between 30 and 428 is 229.

To check that our answer is correct, we subtract 30 from 229 and subtract 229 from 428 and compare the two numbers:

229 - 30 = 199
428 - 229 = 199

As you can see, the halfway number is 199 higher than 30 and 199 lower than 428. Therefore, our halfway between answer of 229 above is correct.
