When you ask "What number is halfway between 78 and 279?" 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=279.
To find the number halfway between 78 and 279, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 78 and 279 into our formula, we get:
(78 + 279)/2 = 178.5
Thus, the number halfway between 78 and 279 is 178.5.
To check that our answer is correct, we subtract 78 from 178.5 and subtract 178.5 from 279 and compare the two numbers:
178.5 - 78 = 100.5
279 - 178.5 = 100.5
As you can see, the halfway number is 100.5 higher than 78 and 100.5 lower than 279. Therefore, our halfway between answer of 178.5 above is correct.
