This math topic involves recognizing and extending patterns based on a specific rule to select the corresponding visual representation. The problems cover various pattern rules such as geometric progressions (e.g., 3x3, 4x4), arithmetic sequences (e.g., adding or subtracting a constant value), and specific number repetitions. Each question provides a rule and asks to choose an image that best represents the pattern described by the rule. The skills practiced include logical reasoning, pattern recognition, and basic arithmetic operations.
