Halfway Between 90 and 850

When you ask "What number is halfway between 90 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=90 and Y=850.

Halfway Between Line

To find the number halfway between 90 and 850, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 850 into our formula, we get:

(90 + 850)/2 = 470

Thus, the number halfway between 90 and 850 is 470.

To check that our answer is correct, we subtract 90 from 470 and subtract 470 from 850 and compare the two numbers:

470 - 90 = 380
850 - 470 = 380

As you can see, the halfway number is 380 higher than 90 and 380 lower than 850. Therefore, our halfway between answer of 470 above is correct.
