(1) Provide an example of two series Zax and be that both diverge, but (ak-be) converges. (2) Provide an example of a series a such that the sequence of partial sums S, is oscillating but the series kak converges. (3) Provide an example of a series Eak such that a 20 for all k and the sequence of partial sums Sn is unbounded. (4) Provide an example of a telescoping series that diverges. (5) Provide an example of a series as such that a diverges but limko ak = 0 (6) Compute (3)* % (;)*, and 2*
