Halfway Between 30 and 842

When you ask "What number is halfway between 30 and 842?" 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=842.

Halfway Between Line

To find the number halfway between 30 and 842, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 842 into our formula, we get:

(30 + 842)/2 = 436

Thus, the number halfway between 30 and 842 is 436.

To check that our answer is correct, we subtract 30 from 436 and subtract 436 from 842 and compare the two numbers:

436 - 30 = 406
842 - 436 = 406

As you can see, the halfway number is 406 higher than 30 and 406 lower than 842. Therefore, our halfway between answer of 436 above is correct.
