Study Notes
Terms and Definitions
- Term of a Sequence: Individual number, figure, or letter within a sequence.
- Sequence: Ordered arrangement of numbers, figures, letters, or other objects demonstrating a specific pattern.
Types of Sequences
- Common Difference: The fixed difference between any two successive terms in an arithmetic sequence.
- Arithmetic Sequence: A sequence where each term is found by adding the same value (common difference) to the previous term; characterized by a constant difference between consecutive terms.
- Geometric Sequence: A sequence where the ratio between any two consecutive terms remains constant; defined by multiplying by the same value (common ratio) to obtain successive terms.
Common Ratios and Differences
- Common Ratio: The constant ratio between consecutive terms in a geometric sequence.
Formulas
- Recursive Formula: Provides a method to determine each term based on the preceding term; essential for understanding sequences that build on prior values.
- Explicit Formula: A direct method to calculate each term by using its position in the sequence; useful for finding the nth term without needing the previous terms.
Specific Formulas (Pending Definitions)
- Explicit Formula for a Geometric Sequence: Not detailed but would involve the initial term and the common ratio.
- Explicit Formula for an Arithmetic Sequence: Not detailed but would involve the first term and common difference.
- Recursive Formula for an Arithmetic Sequence: Not detailed but would iterate using the previous term.
- Recursive Formula for a Geometric Sequence: Not detailed but would also depend on the previous term, utilizing the common ratio.
