  1. What number follows: 17, 19, 23, 29, 37, ?

    Answer: 47

    The differences are 2, 4, 6, 8, 10 — even numbers increasing by 2, so 37 + 10 = 47.

  2. Find the next number: 1, 8, 27, 64, 125, ?

    Answer: 216

    These are perfect cubes (1³, 2³, 3³, …), so the next is 6³ = 216.

  3. What is the missing number in: 6, 11, 21, 41, 81, ?

    Answer: 161

    Each term is approximately doubled and 1 subtracted: 81 × 2 − 1 = 161.

  4. Identify the next term: 2, 6, 18, 54, 162, ?

    Answer: 486

    Each term is multiplied by 3: 162 × 3 = 486.

  5. What comes next: 144, 121, 100, 81, 64, ?

    Answer: 49

    These are descending perfect squares (12², 11², 10², …), so the next is 8² = 64 — wait, next is 7² = 49.

  6. Find the missing number: 3, 7, 15, 31, 63, ?

    Answer: 127

    Each term is doubled and 1 added: 63 × 2 + 1 = 127.

  7. What is next in the sequence: 9, 16, 25, 36, 49, ?

    Answer: 64

    These are perfect squares starting from 3²: the next is 8² = 64.
