Halfway Between 100 and 860

When you ask "What number is halfway between 100 and 860?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=860.

Halfway Between Line

To find the number halfway between 100 and 860, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 860 into our formula, we get:

(100 + 860)/2 = 480

Thus, the number halfway between 100 and 860 is 480.

To check that our answer is correct, we subtract 100 from 480 and subtract 480 from 860 and compare the two numbers:

480 - 100 = 380
860 - 480 = 380

As you can see, the halfway number is 380 higher than 100 and 380 lower than 860. Therefore, our halfway between answer of 480 above is correct.
