Halfway Between 42 and 978

When you ask "What number is halfway between 42 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=42 and Y=978.

Halfway Between Line

To find the number halfway between 42 and 978, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 42 and 978 into our formula, we get:

(42 + 978)/2 = 510

Thus, the number halfway between 42 and 978 is 510.

To check that our answer is correct, we subtract 42 from 510 and subtract 510 from 978 and compare the two numbers:

510 - 42 = 468
978 - 510 = 468

As you can see, the halfway number is 468 higher than 42 and 468 lower than 978. Therefore, our halfway between answer of 510 above is correct.
