Hi all, my test is coming up and while I know how to solve for this type of question, I find myself not sure about the specifics. I know when it says inclusive we do NM+1 for any number mn. However, what if a question says:

“what is the sum of multiples of 4 between 12108” I take the (med)( total of amount numbers) do we just do (10812/4) +1 or just (10812/4)? I’ve seen this question as being inclusive… I can’t find many questions like it for reference but in my notes I don’t have inclusive or exclusive written. would they ever give me this and say exclusive or will it always be inclusive?

same issue with: what is the number of odd numbers between 4199? do we just do (1995/2)+1

for sum of consecutive integers I have been doing n(n+1)/2
