To continue the sequence of tiles shown, the tile indicated by the question mark should be

Seven square tiles in a row: the first is blank, the next two have one dot each, then tiles with 2, 3 and 5 dots, and a dashed tile with a question mark

  • A.A tile with 4 dots, one at each corner
  • B.A tile with 6 dots in two columns of three
  • C.A tile with 8 dots around the edge, the centre empty
  • D.A tile with 9 dots in three rows of three

Answer: C

The missing tile is (C), the tile with 8 dots.

Count the dots in the tiles in order: 0, 1, 1, 2, 3, 5. From the third tile on, each count is the sum of the two before it (1 = 0 + 1, 2 = 1 + 1, 3 = 1 + 2, 5 = 2 + 3), which is the Fibonacci sequence.

The next count is therefore 3 + 5 = 8. Tile (C) has 8 dots, while (A) has 4, (B) 6 and (D) 9, none of which continues the sequence.
