Halfway Between 3 and 978

When you ask "What number is halfway between 3 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=3 and Y=978.

Halfway Between Line

To find the number halfway between 3 and 978, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 3 and 978 into our formula, we get:

(3 + 978)/2 = 490.5

Thus, the number halfway between 3 and 978 is 490.5.

To check that our answer is correct, we subtract 3 from 490.5 and subtract 490.5 from 978 and compare the two numbers:

490.5 - 3 = 487.5
978 - 490.5 = 487.5

As you can see, the halfway number is 487.5 higher than 3 and 487.5 lower than 978. Therefore, our halfway between answer of 490.5 above is correct.
