Give an example of a sequence (an) and (bn) such that (an) and (bn)  diverges and (anbn) converges.  I know how to do it but my teacher used an= 1/n as the converging sequence claiming that it goes to 0?? Isn't it a diverging sequence?? Like his answer was an= 1/n and bn=n so if you multiply them it's 1.
