💡 Key Takeaways
- Recognize and extend common number sequences by spotting the underlying pattern (arithmetic, geometric, Fibonacci, squares, etc.).
- Distinguish arithmetic sequences with a constant difference from geometric sequences with a constant ratio and apply the right rule.
- Compute terms efficiently using nth-term formulas for arithmetic (a_n = a + (n-1)d) and geometric (a_n = a r^(n-1)) sequences.
- Identify missing terms and predict future terms by applying the sequence rule in different contexts.
❓ Frequently Asked Questions
What is a number sequence?
A list of numbers that follows a specific rule, with each term determined by its position in the sequence.
What is the difference between arithmetic and geometric sequences?
Arithmetic: each term adds a constant difference. Geometric: each term multiplies by a constant ratio.
How do you find the nth term of an arithmetic sequence?
If a1 is the first term and d is the common difference, a_n = a1 + (n−1)d.
How do you find the nth term of a geometric sequence?
If a1 is the first term and r is the common ratio, a_n = a1 × r^{n−1}.
What should you do if a sequence isn’t clearly arithmetic or geometric?
Look for patterns like squares, cubes, Fibonacci-like rules, or alternating terms. Check first/second differences to spot quadratic patterns and test candidate rules for the next terms.
