Pattern & Sequence

Pattern & Sequence Difficulty 4 15 questions

Discover the hidden rule behind each sequence. Some follow simple arithmetic, others require recognizing deeper structures like alternating operations, factorials, or descriptive patterns.

Instructions Find the next term in each sequence and explain the rule you discovered. The correct number alone earns partial credit — explaining the pattern earns full credit.
