Halfway Between 78 and 900

When you ask "What number is halfway between 78 and 900?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=78 and Y=900.

Halfway Between Line

To find the number halfway between 78 and 900, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 900 into our formula, we get:

(78 + 900)/2 = 489

Thus, the number halfway between 78 and 900 is 489.

To check that our answer is correct, we subtract 78 from 489 and subtract 489 from 900 and compare the two numbers:

489 - 78 = 411
900 - 489 = 411

As you can see, the halfway number is 411 higher than 78 and 411 lower than 900. Therefore, our halfway between answer of 489 above is correct.
