Number Sequence
How to Play
Game Instructions
- Each puzzle presents a sequence of four numbers.
- Your goal is to identify the pattern and select the correct next number from four options.
- You only get one guess per puzzle, so think carefully!
- Patterns may be arithmetic, geometric, prime, Fibonacci, or more complex.
Why Play Number Sequences?
Sequence puzzles are a gold standard for testing "Fluid Intelligence" (Gf)—the ability to reason and solve novel problems independent of previously acquired knowledge. Unlike arithmetic drills, which rely on memory, sequences require "inductive reasoning."
You must observe specific examples (the numbers 2, 4, 8) and infer a general rule (multiply by 2). This strengthens the brain's ability to recognize relationships and predict future outcomes, a skill critical for fields ranging from computer programming to financial forecasting.
Tips for Success
- Look for simple patterns first: addition, subtraction, multiplication, division.
- Calculate the difference or ratio between consecutive numbers.
- Consider less obvious patterns: squares, cubes, alternating sequences.
- Write down possible next numbers before choosing your answer.
- Use logic and math intuition to rule out unlikely options.
Advanced Pattern Recognition
Calculate the "Gap" (The Delta)
Always write down the difference between each number. If the sequence is 2, 5, 10, 17, the gaps are 3,
5, 7. You can see the gaps themselves are increasing by 2 (odd numbers). This is a
"second-order" sequence.
Check for "Special" Numbers
If the numbers look familiar but don't have a clear gap, check if they are related to
squares (1, 4, 9, 16) or
prime numbers (2, 3, 5, 7, 11). Sometimes the
pattern is n² + 1 (e.g., 2,
5, 10, 17).
Alternating Sequences
If the numbers go up and down (e.g., 2, 5, 3, 6, 4), you likely have
two patterns interwoven. Look at the 1st, 3rd, and 5th numbers separately from the
2nd and 4th.
History of Sequence Puzzles
Number sequences are a staple of psychometric testing, most famously appearing in IQ tests like the Raven's Progressive Matrices. Historically, the study of sequences fascinated mathematicians like Leonardo Fibonacci, whose famous sequence (1, 1, 2, 3, 5...) models patterns found in nature, from pinecones to seashells.

Tips for Number Sequence puzzles?
Look for arithmetic patterns (adding/subtracting the same number), geometric patterns (multiplying/dividing), or more complex rules. Calculate the differences between consecutive numbers. Fibonacci sequences and powers are common patterns too!
