Halfway Between 3 and 8

When you ask "What number is halfway between 3 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=3 and Y=8.

Halfway Between Line

To find the number halfway between 3 and 8, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 3 and 8 into our formula, we get:

(3 + 8)/2 = 5.5

Thus, the number halfway between 3 and 8 is 5.5.

To check that our answer is correct, we subtract 3 from 5.5 and subtract 5.5 from 8 and compare the two numbers:

5.5 - 3 = 2.5
8 - 5.5 = 2.5

As you can see, the halfway number is 2.5 higher than 3 and 2.5 lower than 8. Therefore, our halfway between answer of 5.5 above is correct.
