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.
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.
A pattern: 81, 27, 9, 3, ___. What comes next?
Answer: 1
Each term is divided by 3; 3 ÷ 3 = 1.
In a matrix, each row follows the rule: third number = first × second. Row: 4, 7, ___.
Answer: 28
Applying the rule: 4 × 7 = 28.
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.
A sequence: 5, 10, 20, 40, 80, ___. What is next?
Answer: 160
Each term doubles; 80 × 2 = 160.
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.
