Explanation:
The series follows a multiplication by 2 pattern. 3 x 2 = 6, 6 x 2 = 12, 12 x 2 = 24, and 24 x 2 = 48. Therefore, the next number is 48 x 2 = 96. Number series questions are usually simple if the pattern is identified early. Candidates should test common operations like addition, subtraction, multiplication, division, squares, cubes, and alternating patterns before selecting the answer.
