Halfway Between 78 and 902

When you ask "What number is halfway between 78 and 902?" 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=902.

Halfway Between Line

To find the number halfway between 78 and 902, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 902 into our formula, we get:

(78 + 902)/2 = 490

Thus, the number halfway between 78 and 902 is 490.

To check that our answer is correct, we subtract 78 from 490 and subtract 490 from 902 and compare the two numbers:

490 - 78 = 412
902 - 490 = 412

As you can see, the halfway number is 412 higher than 78 and 412 lower than 902. Therefore, our halfway between answer of 490 above is correct.
