  1. A number series: 1, 1, 2, 3, 5, 8, ___. What comes next?

    Answer: 13

    Each term is the sum of the two preceding terms (Fibonacci), so 5 + 8 = 13.

  2. Each figure in a series has one more circle inside than the previous. The first has 2 circles. How many circles does the 6th figure have?

    Answer: 7

    Starting at 2 and adding 1 for each step: 2 + (6 − 1) = 7.

  3. A pattern: 81, 27, 9, 3, ___. What comes next?

    Answer: 1

    Each term is divided by 3; 3 ÷ 3 = 1.

  4. In a matrix, each row follows the rule: third number = first × second. Row: 4, 7, ___.

    Answer: 28

    Applying the rule: 4 × 7 = 28.

  5. A series of figures shows a star gaining one point each step: 4-point, 5-point, 6-point, ___-point.

    Answer: 7

    Each figure gains one point, so after a 6-point star comes a 7-point star.

  6. A sequence: 5, 10, 20, 40, 80, ___. What is next?

    Answer: 160

    Each term doubles; 80 × 2 = 160.

  7. Letters in a pattern: A, C, F, J, O, ___. What comes next?

    Answer: U

    The gaps increase by 1 each step (+2, +3, +4, +5, +6), so O + 6 = U.
