Halfway Between 30 and 856

When you ask "What number is halfway between 30 and 856?" 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=856.

Halfway Between Line

To find the number halfway between 30 and 856, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 856 into our formula, we get:

(30 + 856)/2 = 443

Thus, the number halfway between 30 and 856 is 443.

To check that our answer is correct, we subtract 30 from 443 and subtract 443 from 856 and compare the two numbers:

443 - 30 = 413
856 - 443 = 413

As you can see, the halfway number is 413 higher than 30 and 413 lower than 856. Therefore, our halfway between answer of 443 above is correct.
