  1. What comes next in the sequence: 3, 6, 12, 24, ___?

    Answer: 48

    Each term is doubled: 3×2=6, 6×2=12, 12×2=24, 24×2=48.

  2. Find the missing number: 2, 5, 10, 17, 26, ___

    Answer: 37

    The differences increase by 2 each time (+3,+5,+7,+9,+11), so 26+11=37.

  3. What letter comes next: A, C, F, J, O, ___?

    Answer: U

    The gaps increase by one each step: +2, +3, +4, +5, +6; O is the 15th letter, and 15+6=21=U.

  4. Which number is next in the sequence: 100, 91, 83, 76, 70, ___?

    Answer: 65

    The decrements shrink by one each step: −9,−8,−7,−6,−5, so 70−5=65.

  5. Which number does NOT belong in this sequence: 7, 11, 15, 19, 22, 27?

    Answer: 22

    The sequence increases by +4 each time (7,11,15,19,23,27), so 22 is incorrect — it should be 23.

  6. What comes next: 2, 3, 5, 8, 13, 21, ___?

    Answer: 34

    Each term is the sum of the two preceding terms (Fibonacci): 13+21=34.

  7. Complete the series: 1, 4, 9, 16, 25, ___

    Answer: 36

    These are perfect squares: 1²,2²,3²,4²,5²,6²=36.
