[SOLVED] Sum of numbers between 2 numbers, formula?
Sorry if this is in the wrong section, I did maths a year and a bit back in high school and im doing computing at uni, and I'm not sure on the exact formula I need.
I need it to double check that my program is outputting the right sum.
I need the formula to calculate the sum of the numbers between 200 and 300 inclusively.
the sum my program is giving me is 25250
I cant even remember doing this with numbers being inclusive or exclusive.
so could someone please explain the difference between inclusive and exclusive numbers, and the formula I need to be using?
