Halfway Between 100 and 842

When you ask "What number is halfway between 100 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=100 and Y=842.

Halfway Between Line

To find the number halfway between 100 and 842, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 842 into our formula, we get:

(100 + 842)/2 = 471

Thus, the number halfway between 100 and 842 is 471.

To check that our answer is correct, we subtract 100 from 471 and subtract 471 from 842 and compare the two numbers:

471 - 100 = 371
842 - 471 = 371

As you can see, the halfway number is 371 higher than 100 and 371 lower than 842. Therefore, our halfway between answer of 471 above is correct.
