Halfway Between 1 and 660

When you ask "What number is halfway between 1 and 660?" 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=660.

Halfway Between Line

To find the number halfway between 1 and 660, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 660 into our formula, we get:

(1 + 660)/2 = 330.5

Thus, the number halfway between 1 and 660 is 330.5.

To check that our answer is correct, we subtract 1 from 330.5 and subtract 330.5 from 660 and compare the two numbers:

330.5 - 1 = 329.5
660 - 330.5 = 329.5

As you can see, the halfway number is 329.5 higher than 1 and 329.5 lower than 660. Therefore, our halfway between answer of 330.5 above is correct.
