Halfway Between 66 and 670

When you ask "What number is halfway between 66 and 670?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=66 and Y=670.

Halfway Between Line

To find the number halfway between 66 and 670, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 670 into our formula, we get:

(66 + 670)/2 = 368

Thus, the number halfway between 66 and 670 is 368.

To check that our answer is correct, we subtract 66 from 368 and subtract 368 from 670 and compare the two numbers:

368 - 66 = 302
670 - 368 = 302

As you can see, the halfway number is 302 higher than 66 and 302 lower than 670. Therefore, our halfway between answer of 368 above is correct.
