intro to sequences



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.
