Halfway Between 9 and 842

When you ask "What number is halfway between 9 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=9 and Y=842.

Halfway Between Line

To find the number halfway between 9 and 842, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 842 into our formula, we get:

(9 + 842)/2 = 425.5

Thus, the number halfway between 9 and 842 is 425.5.

To check that our answer is correct, we subtract 9 from 425.5 and subtract 425.5 from 842 and compare the two numbers:

425.5 - 9 = 416.5
842 - 425.5 = 416.5

As you can see, the halfway number is 416.5 higher than 9 and 416.5 lower than 842. Therefore, our halfway between answer of 425.5 above is correct.
