 +10 Does this condition imply convergence of $\sum_k x_k$? +25 Is it possible that $\sum_{n \geq 1} n a_n^2$ converges but $\sum_{n \geq 1} a_n$ does not +35 Problems with a proof that every real sequence has a monotonic subsequence +2 How to show that the limit of this sequence is $L=4$ (ex.8.11 Mathematical Analysis 2nd ed.- Apostol)
