Halfway Between 78 and 671

When you ask "What number is halfway between 78 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=78 and Y=671.

Halfway Between Line

To find the number halfway between 78 and 671, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 671 into our formula, we get:

(78 + 671)/2 = 374.5

Thus, the number halfway between 78 and 671 is 374.5.

To check that our answer is correct, we subtract 78 from 374.5 and subtract 374.5 from 671 and compare the two numbers:

374.5 - 78 = 296.5
671 - 374.5 = 296.5

As you can see, the halfway number is 296.5 higher than 78 and 296.5 lower than 671. Therefore, our halfway between answer of 374.5 above is correct.
