Summary

The essence of sequences in mathematics, particularly for the GMAT exam, revolves around understanding their ordered nature, discerning patterns, and applying algebraic formulas to solve related problems.

- Sequences are ordered lists of numbers following identifiable patterns, crucial for solving GMAT problems.
- Notation involves representing sequences with a lowercase letter and individual terms with numerical subscripts, where 'n' denotes the position in the sequence.
- Algebraic formulas for sequences allow for the determination of any term in the sequence, providing a method to solve for specific terms or differences between terms.
- Understanding basic sequence patterns, such as sequences of integers, odd numbers, even numbers, multiples, and powers, is foundational.
- Practice problems in the GMAT context often involve algebraic sequences defined by fractions or other operations, requiring the test taker to find term values or differences.
