Sequences and Series exercises text

[medwatt]

Hello,
In Calculus 2, sequences and series are introduced and do I have to say that most of the examples are trivial and even the exercises are either trivial or those that require experience. I hope someone can suggest a book where one can learn solving not-so-obvious series problems that might be convoluted and also provide techniques how to compare series.
Thank You.
PS- I am sorry to be posting this in the wrong section but was unable to do so in the books section.
