Halfway Between 4 and 978

When you ask "What number is halfway between 4 and 978?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=4 and Y=978.

Halfway Between Line

To find the number halfway between 4 and 978, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 978 into our formula, we get:

(4 + 978)/2 = 491

Thus, the number halfway between 4 and 978 is 491.

To check that our answer is correct, we subtract 4 from 491 and subtract 491 from 978 and compare the two numbers:

491 - 4 = 487
978 - 491 = 487

As you can see, the halfway number is 487 higher than 4 and 487 lower than 978. Therefore, our halfway between answer of 491 above is correct.
