Halfway Between 5 and 665

When you ask "What number is halfway between 5 and 665?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=5 and Y=665.

Halfway Between Line

To find the number halfway between 5 and 665, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 665 into our formula, we get:

(5 + 665)/2 = 335

Thus, the number halfway between 5 and 665 is 335.

To check that our answer is correct, we subtract 5 from 335 and subtract 335 from 665 and compare the two numbers:

335 - 5 = 330
665 - 335 = 330

As you can see, the halfway number is 330 higher than 5 and 330 lower than 665. Therefore, our halfway between answer of 335 above is correct.
