  1. What comes next? 3, 6, 12, 24, 48, ___

    Each term doubles the previous one, so 48 × 2 = 96.

  2. What comes next? 100, 91, 83, 76, 70, ___

    Answer: 65

    The differences decrease by 1 each step: −9, −8, −7, −6, −5, so next is 70 − 5 = 65.

  3. What comes next? 2, 3, 5, 8, 13, 21, ___

    This is the Fibonacci sequence where each term is the sum of the two before it: 13 + 21 = 34.

    Answer: 80

    Differences are +5, +10, +15, +20, +25, so 55 + 25 = 80.

  5. What comes next? 729, 243, 81, 27, ___

    Answer: 9

    Each term is divided by 3, so 27 ÷ 3 = 9.

  6. What comes next? 4, 9, 16, 25, 36, ___

    Answer: 49

    These are perfect squares: 2², 3², 4², 5², 6², so next is 7² = 49.

  7. What comes next? 1, 4, 13, 40, 121, ___

    Answer: 364

    Each term is multiplied by 3 then 1 is added: 121 × 3 + 1 = 364.
