In a sequence of shapes: triangle, square, triangle, square, triangle, what is the next shape?

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

Answer: (A)

Pattern recognition shows a simple alternation between two shapes. The sequence goes triangle, square, triangle, square, triangle, so the next step continues the same switch and becomes square. The other options don’t fit because they would introduce a new shape or repeat the triangle in a way that breaks the established alternation (a circle or hexagon would add a new shape, and another triangle would break the pattern of alternating between the two shapes).
