Halfway Between 13 and 856

When you ask "What number is halfway between 13 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=13 and Y=856.

Halfway Between Line

To find the number halfway between 13 and 856, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 856 into our formula, we get:

(13 + 856)/2 = 434.5

Thus, the number halfway between 13 and 856 is 434.5.

To check that our answer is correct, we subtract 13 from 434.5 and subtract 434.5 from 856 and compare the two numbers:

434.5 - 13 = 421.5
856 - 434.5 = 421.5

As you can see, the halfway number is 421.5 higher than 13 and 421.5 lower than 856. Therefore, our halfway between answer of 434.5 above is correct.
