Halfway Between 30 and 850

When you ask "What number is halfway between 30 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=30 and Y=850.

Halfway Between Line

To find the number halfway between 30 and 850, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 850 into our formula, we get:

(30 + 850)/2 = 440

Thus, the number halfway between 30 and 850 is 440.

To check that our answer is correct, we subtract 30 from 440 and subtract 440 from 850 and compare the two numbers:

440 - 30 = 410
850 - 440 = 410

As you can see, the halfway number is 410 higher than 30 and 410 lower than 850. Therefore, our halfway between answer of 440 above is correct.
