Halfway Between 100 and 802

When you ask "What number is halfway between 100 and 802?" 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=802.

Halfway Between Line

To find the number halfway between 100 and 802, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 802 into our formula, we get:

(100 + 802)/2 = 451

Thus, the number halfway between 100 and 802 is 451.

To check that our answer is correct, we subtract 100 from 451 and subtract 451 from 802 and compare the two numbers:

451 - 100 = 351
802 - 451 = 351

As you can see, the halfway number is 351 higher than 100 and 351 lower than 802. Therefore, our halfway between answer of 451 above is correct.
