  1. Identify the type of sequence: 3, 6, 12, 24, 48

    Answer: Geometric with r=2

    Ratios: 6/3=2, 12/6=2, 24/12=2, 48/24=2. Constant ratio r=2, so this is geometric.

  2. What are the next two terms: 1, 2, 4, 7, 11, 16, ___

    Answer: 21, 27

    Differences: 1, 2, 3, 4, 5 — increasing by 1. Next differences: 5 and 6. 16+5=21, 21+6=27.

  3. The sequence uses the rule: multiply by 2, subtract 3. Starting from 5, what is the 4th term?

    Answer: 19

    5 → 5×2-3=7 → 7×2-3=11 → 11×2-3=19. 4th term is 19.

  4. Find the missing number: 2, 6, 18, ___, 162, 486

    Answer: 54

    Geometric sequence with r=3: 2×3=6, 6×3=18, 18×3=54, 54×3=162, 162×3=486.

  5. A pattern of shapes alternates: ○ △ □ ○ △ □ ○ ... What is the 14th shape?

    Answer: △

    Pattern repeats every 3: position mod 3. 14 mod 3 = 2 (remainder). Position 2 in the cycle = △.

  6. What is the sum of the first 6 terms of the arithmetic sequence: 4, 7, 10, 13, 16, 19?

    Answer: 69

    4+7+10+13+16+19 = 69.
