  1. What comes next in the series? 1, 3, 9, 27, __

    Answer: 81

    Each number is multiplied by 3, so 27 × 3 = 81.

  2. Find the next number: 1, 2, 4, 7, 11, __

    Answer: 16

    The differences increase by 1 each time (+1, +2, +3, +4, +5), so 11 + 5 = 16.

  3. What is the next number? 10, 7, 9, 6, 8, 5, __

    Answer: 7

    Two interleaved decreasing sequences: 10, 9, 8, 7 and 7, 6, 5; the next odd-position term is 7.

  4. What number comes next? 1, 4, 9, 16, 25, __

    Answer: 36

    These are perfect squares (1², 2², 3², 4², 5², 6²), so the next is 6² = 36.

  5. Find the missing number: 64, 32, 16, 8, __

    Answer: 4

    Each number is divided by 2, so 8 ÷ 2 = 4.

  6. What continues this pattern? 2, 4, 3, 6, 4, 8, __

    Answer: 5

    Odd-position terms (2, 3, 4, ...) increase by 1 each time, so the next odd-position term is 5.

  7. What number comes next? 4, 8, 12, 16, 20, __

    Answer: 24

    Each number increases by 4 (multiples of 4), so 20 + 4 = 24.
