Halfway Between 100 and 850

When you ask "What number is halfway between 100 and 850?" 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=850.

Halfway Between Line

To find the number halfway between 100 and 850, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 850 into our formula, we get:

(100 + 850)/2 = 475

Thus, the number halfway between 100 and 850 is 475.

To check that our answer is correct, we subtract 100 from 475 and subtract 475 from 850 and compare the two numbers:

475 - 100 = 375
850 - 475 = 375

As you can see, the halfway number is 375 higher than 100 and 375 lower than 850. Therefore, our halfway between answer of 475 above is correct.
