When you ask "What number is halfway between 68 and 778?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=68 and Y=778.
To find the number halfway between 68 and 778, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 68 and 778 into our formula, we get:
(68 + 778)/2 = 423
Thus, the number halfway between 68 and 778 is 423.
To check that our answer is correct, we subtract 68 from 423 and subtract 423 from 778 and compare the two numbers:
423 - 68 = 355
778 - 423 = 355
As you can see, the halfway number is 355 higher than 68 and 355 lower than 778. Therefore, our halfway between answer of 423 above is correct.
