  1. What number comes next in the series: 3, 6, 11, 18, 27, ?

    Answer: 38

    The differences are 3, 5, 7, 9, 11 — odd numbers increasing by 2, so 27 + 11 = 38.

  2. Find the missing number: 81, 27, 9, 3, ?

    Answer: 1

    Each term is divided by 3, so 3 ÷ 3 = 1.

  3. What is the next number: 2, 5, 11, 23, 47, ?

    Answer: 95

    Each term is doubled and then 1 is added: 47 × 2 + 1 = 95.

  4. Complete the pattern: 1, 4, 9, 16, 25, ?

    Answer: 36

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

  5. What replaces the question mark: 7, 14, 28, 56, ?

    Answer: 112

    Each term doubles: 56 × 2 = 112.

  6. Find the missing value: 100, 91, 81, 70, 58, ?

    Answer: 45

    Differences are 9, 10, 11, 12, 13 — so 58 − 13 = 45.

  7. What is next in this sequence: 0, 1, 3, 6, 10, 15, ?

    Answer: 21

    These are triangular numbers; differences increase by 1 each time, so 15 + 6 = 21.
