Cheat Sheet
Arithmetic Progressions -
Arithmetic sequences follow the formula aₙ = a + (n - 1)d, where d is the common difference. Spot this in a pattern quiz by checking if successive terms increase or decrease by the same amount. For example, in 3, 7, 11, 15,… the constant difference d=4 makes predicting the next term immediate (19).
Geometric Sequences -
In a number sequence quiz, geometric patterns multiply by a constant ratio r: aₙ = a·r❿❻¹. Test for this by dividing consecutive terms - if the ratio stays constant (e.g., 2, 6, 18, 54… has r=3), you've found the rule. Many math pattern quizzes feature this type, so remembering "divide to verify" is a handy mnemonic.
Second Differences & Quadratic Patterns -
When first differences aren't constant, compute second differences: a constant value indicates a quadratic rule of form an² + bn + c. According to MIT OpenCourseWare, this helps decode puzzles like 2, 6, 12, 20… where second differences are all 2, implying n² + n. Use simple tables to track differences side by side.
Fibonacci & Recurrence Relations -
The famous Fibonacci sequence (1, 1, 2, 3, 5, 8…) follows Fₙ = Fₙ₋ + Fₙ₋₂, a core example in sequence puzzles researched by the OEIS. Look for patterns where each term sums the two preceding ones - this trick surfaces often in advanced pattern quizzes. A quick memory phrase: "last two make the next," keeps your focus sharp.
Prime & Special Number Patterns -
Some sequence puzzles hinge on prime numbers (2, 3, 5, 7, 11…) or other sets like triangular or square numbers. The Prime Pages and Wolfram MathWorld provide extensive lists to verify candidates. If differences or ratios fail, consider testing primality or known figurate forms to crack these tricky number patterns.
