So the book is saying that this series diverges, i have learned my lesson and have stopped doubting the authors of this book but i don't understand how this series diverges. ok i can use the comparison test using 1/3n and 1/3n converges, since 1/(3n+1) is less than 1/3n i don't see how it will not also converge? plug in infinity to 1/3n and you get 0 which converges
