Halfway Between 11 and 671

When you ask "What number is halfway between 11 and 671?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=11 and Y=671.

Halfway Between Line

To find the number halfway between 11 and 671, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 671 into our formula, we get:

(11 + 671)/2 = 341

Thus, the number halfway between 11 and 671 is 341.

To check that our answer is correct, we subtract 11 from 341 and subtract 341 from 671 and compare the two numbers:

341 - 11 = 330
671 - 341 = 330

As you can see, the halfway number is 330 higher than 11 and 330 lower than 671. Therefore, our halfway between answer of 341 above is correct.
