The document you uploaded contains exercises on sequences ("ciągi") and limits of sequences ("granice ciągów"). Below are the key tasks from the first two sections of the document:

1. Monotonicity of sequences: Investigate whether the following sequences are increasing or decreasing:

   • $a_n = \frac{1}{3n}$
   • $b_n = 2n - 2$
   • $c_n = \frac{n^2}{n+2}$

2. Limits of sequences: Calculate the limits of the following sequences (if they exist):

   • $\lim_{n \to \infty} \frac{17n + 35}{3n + 1}$
   • $\lim_{n \to \infty} \frac{3n^3 + 23n^2 + 52n + 45}{n^3 + 2n^2 + 1}$
   • $\lim_{n \to \infty} \frac{2n^2 + 5n + 1}{n^2 + 25}$
   • And several other limit expressions.

Would you like me to solve any specific problem from this document or provide a detailed solution for a sequence? Feel free to choose a task.
