  1. Find the next number: 1, 2, 4, 7, 11, 16, ?

    Answer: 22

    The differences are 1, 2, 3, 4, 5, so the next difference is 6 and 16 + 6 = 22.

  2. What comes next: 256, 64, 16, 4, ?

    Answer: 1

    Each term is divided by 4, so 4 ÷ 4 = 1.

  3. Complete the sequence: 11, 22, 33, 44, 55, ?

    Answer: 66

    Each term increases by 11, so 55 + 11 = 66.

  4. Find the missing term: 0, 1, 8, 27, 64, ?

    Answer: 125

    These are perfect cubes (0³, 1³, 2³, 3³, 4³), so the next is 5³ = 125.

  5. What is the next number: 1000, 500, 250, 125, ?

    Answer: 62.5

    Each term is halved (divided by 2), so 125 ÷ 2 = 62.5.

  6. Complete the series: 2, 3, 5, 8, 12, 17, ?

    Answer: 23

    The differences between terms are 1, 2, 3, 4, 5, 6 — increasing by 1 each time, so 17 + 6 = 23.

  7. Find the next term: 5, 25, 125, 625, ?

    Answer: 3125

    Each term is multiplied by 5, so 625 × 5 = 3125.
