In a pattern where a triangle alternates with a square (triangle, square, triangle, square, ...), what is the 6th symbol?

• A. Triangle
• B. Square
• C. Circle
• D. Pentagon

Answer: (B)

The pattern steadily alternates between two shapes: triangle, then square, then triangle, then square, and so on. This means after a triangle comes a square, and after a square comes a triangle. Since the sequence up to now ends with a triangle, the next symbol must be a square. The other shapes listed don’t fit the ongoing two-shape alternation. So the symbol that comes next is square.
