About the methodology
Number sequence tests are part of classical psychometrics and are widely used to assess fluid intelligence (Gf) according to the Cattell-Horn-Carroll (CHC) model. Fluid intelligence is responsible for the ability to solve novel problems without relying on prior experience or learned knowledge.
The methodology is based on inductive reasoning: the test-taker must identify the rule governing the sequence and extrapolate it to the next element. Research shows that this ability correlates strongly with success in STEM fields (science, technology, engineering, mathematics) and is one of the most reliable predictors of learning ability.
Our test includes tasks of increasing difficulty: from simple arithmetic progressions (constant difference between adjacent elements) to combined patterns with multiple simultaneously operating rules. The dynamic scoring system considers both answer correctness and solution speed, enabling a more precise assessment of cognitive efficiency.

All testsFrequently asked questions
What does this test measure?
The test assesses fluid intelligence: the ability to find patterns in number sequences, apply inductive reasoning, and switch between different pattern types. This is a key component of analytical thinking.
How long does it take?
Maximum time: 20 minutes (40 seconds for each of the 30 questions). Most participants complete the test in 12-16 minutes.
How does the scoring system work?
Each correct answer earns 100 base points plus a speed bonus (up to 100 additional points for an instant answer). Your final rank is determined by the percentage of correct answers.
Can I use a calculator?
A calculator is not forbidden, but the test tracks tab switching. All tasks are designed so that no complex calculations are needed: the key is understanding the pattern, not arithmetic.
Can I retake the test?
Yes, you can take the test an unlimited number of times. Results are saved so you can track your progress.
Instructions
You will be presented with a series of 30 number sequences. Each one contains a hidden pattern: it could be an arithmetic or geometric progression, a Fibonacci series, alternating operations, or more complex combined patterns. Your task: identify the pattern and choose the correct continuation from four options. You have 40 seconds per question. Difficulty increases gradually. Answer independently: the test tracks tab switching. Correct answers earn base points plus a speed bonus. After the test, you'll receive a detailed review of each answer with pattern explanations.
