Look at this series: (1/9), (1/3), 1, ____ , 9, ... What number should fill…

Answer: 3

Explanation:

• The pattern multiplies each term by 3 to get the next term.

• Check the sequence step by step: (1/9) × 3 = (1/3); (1/3) × 3 = 1; 1 × 3 = 3; 3 × 3 = 9.

• Therefore the missing number between 1 and 9 is 3.
