Halfway Between 13 and 978

When you ask "What number is halfway between 13 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=13 and Y=978.

Halfway Between Line

To find the number halfway between 13 and 978, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 978 into our formula, we get:

(13 + 978)/2 = 495.5

Thus, the number halfway between 13 and 978 is 495.5.

To check that our answer is correct, we subtract 13 from 495.5 and subtract 495.5 from 978 and compare the two numbers:

495.5 - 13 = 482.5
978 - 495.5 = 482.5

As you can see, the halfway number is 482.5 higher than 13 and 482.5 lower than 978. Therefore, our halfway between answer of 495.5 above is correct.
