Study Notes
Finding the Next Term in a Sequence
- A sequence is a list of numbers that follow a specific pattern or rule.
- To find the next term in a sequence, identify the pattern or rule that governs the sequence.
Arithmetic Sequences
- An arithmetic sequence is a sequence where each term differs from the previous term by a common difference.
- To find the next term in an arithmetic sequence, add the common difference to the previous term.
- Examples:
- 2, 5, 8, 11, 14 (common difference: 3)
- 5, 9, 13, 17 (common difference: 4)
- 27, 21, 15, 9 (common difference: -6)
Geometric Sequences
- A geometric sequence is a sequence where each term differs from the previous term by a common ratio.
- To find the next term in a geometric sequence, multiply the previous term by the common ratio.
- Examples:
- 3, 6, 12, 24 (common ratio: 2)
- 4, 12, 36 (common ratio: 3)
Other Sequence Patterns
- Some sequences may not follow an arithmetic or geometric pattern, but may have other patterns such as exponents (e.g., 1, 4, 9, 16, ...) or fractions (e.g., 3/4, 5/7, 7/10, ...).
- To find the next term in such sequences, identify the underlying pattern and apply it to find the next term.
Examples and Applications
- Finding the next term in a sequence can be applied to various problems, such as:
- Series of numbers: 2, 5, 8, 11, 14, ...
- Exponents: 1, 4, 9, 16, ...
- Fractions: 3/4, 5/7, 7/10, ...
- Real-world problems: population growth, financial calculations, and more.
Tips and Tricks
- When dealing with fractions, separate the numerator and denominator to identify patterns.
- Look for patterns in the sequence, such as common differences or ratios.
- Use the pattern to find the next term in the sequence.

Arithmetic Sequences
- Each term in an arithmetic sequence differs from the previous term by a common difference.
- To find the next term, add the common difference to the previous term.
- Examples of arithmetic sequences:
- 2, 5, 8, 11, 14 (common difference: 3)
- 5, 9, 13, 17 (common difference: 4)
- 27, 21, 15, 9 (common difference: -6)
Geometric Sequences
- Each term in a geometric sequence differs from the previous term by a common ratio.
- To find the next term, multiply the previous term by the common ratio.
- Examples of geometric sequences:
- 3, 6, 12, 24 (common ratio: 2)
- 4, 12, 36 (common ratio: 3)
Other Sequence Patterns
- Some sequences follow exponential or fractional patterns.
- Examples of exponential sequences: 1, 4, 9, 16,...
- Examples of fractional sequences: 3/4, 5/7, 7/10,...
- Identify the underlying pattern and apply it to find the next term.
Examples and Applications
- Finding the next term in a sequence has applications in:
- Series of numbers: 2, 5, 8, 11, 14,...
- Exponential sequences: 1, 4, 9, 16,...
