Halfway Between 20 and 850

When you ask "What number is halfway between 20 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=20 and Y=850.

Halfway Between Line

To find the number halfway between 20 and 850, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 850 into our formula, we get:

(20 + 850)/2 = 435

Thus, the number halfway between 20 and 850 is 435.

To check that our answer is correct, we subtract 20 from 435 and subtract 435 from 850 and compare the two numbers:

435 - 20 = 415
850 - 435 = 415

As you can see, the halfway number is 415 higher than 20 and 415 lower than 850. Therefore, our halfway between answer of 435 above is correct.
