Question:medium

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

Show Hint

Count the dots on each tile: 0, 1, 1, 2, 3, 5. Check if each number is the sum of the two before it (the Fibonacci rule) and use that to find the missing count.

The Correct Option is C

Solution and Explanation

The seven tiles form a sequence where each tile is defined only by how many dots it carries. Instead of thinking about shapes, we can turn this into a pure number pattern and hunt for the rule that connects consecutive terms.

  1. Tile counts: reading the dots tile by tile gives the list $0, 1, 1, 2, 3, 5$, and we need the seventh term.
  2. Testing a sum rule: check if each term equals the sum of the two terms right before it. $0+1=1$, $1+1=2$, $1+2=3$, $2+3=5$. Every check passes, so the rule "add the previous two terms" explains the whole list. This is the well known Fibonacci rule.
  3. Extending the rule: applying the same addition to the last two known terms, $3+5=8$, gives the count needed on the seventh tile.
  4. Matching to the options: option (A) has 4 dots, option (B) has 6 dots, option (C) has 8 dots, and option (D) has 9 dots. Only option (C) carries the required 8 dots.

The tile that continues the pattern must show 8 dots, which is exactly what option (C) shows, so option (C) is correct.

Let's summarize:

  • Counting the dots turns a picture puzzle into a number sequence.
  • The sequence $0, 1, 1, 2, 3, 5, 8$ is the Fibonacci sequence, where each term is the sum of the two before it.
  • The missing tile needs 8 dots, matching option (C).

So the correct tile is the one with 8 dots.
