When you ask "What number is halfway between 78 and 259?" 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=259.
To find the number halfway between 78 and 259, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 78 and 259 into our formula, we get:
(78 + 259)/2 = 168.5
Thus, the number halfway between 78 and 259 is 168.5.
To check that our answer is correct, we subtract 78 from 168.5 and subtract 168.5 from 259 and compare the two numbers:
168.5 - 78 = 90.5
259 - 168.5 = 90.5
As you can see, the halfway number is 90.5 higher than 78 and 90.5 lower than 259. Therefore, our halfway between answer of 168.5 above is correct.
