An = 3n / (12n+15)

Series n=1 infinity (An) (Sorry,i dont know the symbols)

Does this converge or diverge? if it diverges does it go to infinity or minus infinity? If it converges what would be the limit?

Sequence {An}

Same question.

For the series, i said that it goes to infinity, but im guessing its wrong.

FOr the sequence, converge to 0? or diverges. not sure.
