Halfway Between 15 and 671

When you ask "What number is halfway between 15 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=15 and Y=671.

Halfway Between Line

To find the number halfway between 15 and 671, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 671 into our formula, we get:

(15 + 671)/2 = 343

Thus, the number halfway between 15 and 671 is 343.

To check that our answer is correct, we subtract 15 from 343 and subtract 343 from 671 and compare the two numbers:

343 - 15 = 328
671 - 343 = 328

As you can see, the halfway number is 328 higher than 15 and 328 lower than 671. Therefore, our halfway between answer of 343 above is correct.
