Summary

Understanding sequences is crucial for GRE prep, focusing on their patterns, notation, and algebraic definitions to solve related problems.

- Sequences are ordered lists of numbers following identifiable patterns, essential for the GRE exam.
- Notation involves representing sequences with a lowercase letter and individual terms with numerical subscripts, e.g., a sub 5 = 28.
- Algebraic formulas for sequences allow for the determination of any term in the sequence, facilitating the solving of GRE questions.
- Practice problems demonstrate how to apply knowledge of sequences to find term values and differences, emphasizing the importance of understanding sequence patterns and algebraic definitions.
- Understanding basic sequence patterns and their algebraic representations is foundational for tackling GRE sequence problems.
