9.8 Definition. For a sequence (sn), we write lim sn = +∞o provided for each M> 0 there is a number N such that n> N implies Sn > M. In this case we say the sequence diverges to +∞. Similarly, we write lim sn= -∞ provided for each M<0 there is a number N such that n> N implies Sn < M. §9. Limit Theorems for Seque
