What is Class 11 Sequence and Series Formulas about?

The document defines key terms related to sequences and series. It explains that a sequence is an ordered set of numbers, while a series is a sequence with alternating addition signs between terms. There are two main types of sequences: arithmetic progressions (AP) and geometric progressions (GP). An AP has a constant difference between consecutive terms, while a GP has a constant ratio between consecutive terms. Formulas are provided for writing the nth term and finding the sum of terms for an AP. Examples
