Cheat Sheet
- Arithmetic Progressions (AP) -
In an AP, each term increases by a constant difference d following the formula aₙ = a + (n−1)d, which helps you forecast future terms. Master this concept to quickly solve iq test numbers or sequence exam items (MIT OpenCourseWare). For instance, in 4, 9, 14, … the constant difference is 5, so the next term is 19.
- Geometric Progressions (GP) -
A GP features multiplication by a constant ratio r, with aₙ = a·r❿❻¹ to find any term in the series. Recognizing GP patterns is essential for sequence series quiz and number patterns test sections (University of Cambridge). For example, in 3, 6, 12, … the ratio is 2, so the fourth term is 24.
- Recursive Sequences & Fibonacci -
Recursive sequences define each term based on previous ones, like the Fibonacci rule Fₙ = Fₙ₋ + Fₙ₋₂. Familiarity with this concept boosts your speed on numeric sequence challenge questions in iq test numbers assessments (Fibonacci Quarterly). A handy mnemonic is "add the last two" to get 1, 1, 2, 3, 5, 8, ….
- Difference Method for Polynomial Sequences -
By computing first and second differences, you can detect linear, quadratic, and higher-order patterns in number sequences. This technique is crucial for acing sequence exam problems involving polynomial trends (Stanford Mathematics). For example, 2, 6, 12, 20, … has second differences constant at 2, indicating a quadratic pattern.
- Special Numeric Patterns -
Key sequences include squares (n²), cubes (n³), primes, and triangular numbers (n(n+1)/2), all appearing frequently in number patterns test and sequence series quiz contexts. Memorizing formulas like "n² for squares" or using the prime sieve helps you recognize these quickly (Oxford University). For example, the squares sequence 1, 4, 9, 16, … uses n² for n=1,2,3,4.
