Answer D

Find the next domino by extending the exact rule used in the shown sequence.

  1. Observe top and bottom lanes

    Use the visible tiles [2|0], [0|2], [2|2], [2|4], [4|6] to detect how values evolve.

  2. Identify the generation rule

    Each new value comes from top + bottom (mod 7).

  3. How each piece connects to the next

    [4|6] follows Each new value comes from top + bottom (mod 7).. So the next tile must be [6|3].

  4. Apply one more step

    Starting from [4|6], applying the rule yields [6|3] — the only option that continues the sequence.

The next tile must be [6|3]; that option is the only consistent continuation.
