Halfway Between 40 and 670

When you ask "What number is halfway between 40 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=40 and Y=670.

Halfway Between Line

To find the number halfway between 40 and 670, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 670 into our formula, we get:

(40 + 670)/2 = 355

Thus, the number halfway between 40 and 670 is 355.

To check that our answer is correct, we subtract 40 from 355 and subtract 355 from 670 and compare the two numbers:

355 - 40 = 315
670 - 355 = 315

As you can see, the halfway number is 315 higher than 40 and 315 lower than 670. Therefore, our halfway between answer of 355 above is correct.
