In a sequence of blocks: black square, white square, black square, white square, what is the 5th item?

• A. White square
• B. White circle
• C. Black circle
• D. Black square

Answer: (D)

The sequence keeps the same shape (a square) while alternating colors with each step. Starting black, then white, then black, then white, the fifth item follows the same alternation, so it remains black and is a square. The other options don’t fit because they change the shape (circles) or break the color pattern for this position (a white square would occur at even positions, not the fifth).
