Series & Analogy
Series and Analogy problems test your ability to track changes across an extended chain of shapes or match paired transformations (e.g., how Shape A turns into Shape B dictates how Shape C must turn into Shape D).
Fundamental Principles
Paired Transformation Matrix
An analogy rule requiring the second pair of abstract shapes to copy the exact geometric edits, flips, or size changes used in the first pair.
Essential Formulation Tips
- For series questions, make sure your rule works consistently across the entire chain (from step 1 to 2, 2 to 3, and 3 to 4) before choosing your final answer.
- In analogy problems, write down a quick description of the change (e.g., 'Inverts upside down and doubles its outer lines') to use as a checklist for the next pair.
Shortcut Execution Techniques
- The Element Isolation Filter: Don't look at the choices as whole drawings right away. Isolate one detail (like a shaded corner), find its rule, and use it to cross off wrong options instantly.
Contextual Inquiries (FAQs)
Q: What should I do if a series seems to follow two different rules at the same time?
A: Check if it is an alternating series where odd boxes (1, 3, 5) follow one rule while even boxes (2, 4) follow a separate pattern.
Example Breakdown: Decoding Figure Analogy Shifts
Classic shape analogy transformation tracking.Break down the changes in the first pair: 1. The main shape grows larger. 2. Its color changes from solid black to white. 3. A new small black circle is added inside.
Apply these exact changes to the black square: 1. Make the square larger. 2. Change its color from black to white. 3. Add a small black circle right in the center.
Conclusion: The correct match is a large white square containing a small black circle inside.
