Halfway Between 1 and 8

When you ask "What number is halfway between 1 and 8?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=1 and Y=8.

Halfway Between Line

To find the number halfway between 1 and 8, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 8 into our formula, we get:

(1 + 8)/2 = 4.5

Thus, the number halfway between 1 and 8 is 4.5.

To check that our answer is correct, we subtract 1 from 4.5 and subtract 4.5 from 8 and compare the two numbers:

4.5 - 1 = 3.5
8 - 4.5 = 3.5

As you can see, the halfway number is 3.5 higher than 1 and 3.5 lower than 8. Therefore, our halfway between answer of 4.5 above is correct.
