Halfway Between 18 and 978

When you ask "What number is halfway between 18 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=18 and Y=978.

Halfway Between Line

To find the number halfway between 18 and 978, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 18 and 978 into our formula, we get:

(18 + 978)/2 = 498

Thus, the number halfway between 18 and 978 is 498.

To check that our answer is correct, we subtract 18 from 498 and subtract 498 from 978 and compare the two numbers:

498 - 18 = 480
978 - 498 = 480

As you can see, the halfway number is 480 higher than 18 and 480 lower than 978. Therefore, our halfway between answer of 498 above is correct.
