We covered absolute values and complex numbers; see pp. 12–15 of Rudin’s Principles of Mathematical Analysis (3rd edition).

We then started Chapter II: Sequences, covering basic properties of sequences, bounded sequences, subsequences, and accumulation points. Related material can be found in Chapter 3 of Rudin’s book. Note that Rudin uses the term “subsequential limit” for what we call an “accumulation point” of a sequence.
