Number series (missing term): Identify the value that correctly continues the alternating multiplication pattern. Given sequence: 1, 2, 3, 6, 9, 18, ?, 54 Pattern hint: terms alternate between ×2 and ×1.5 (i.e., ×3/2). Choose the correct missing number.

Difficulty: Easy

Correct Answer: 27

Explanation:

Given dataSequence: 1, 2, 3, 6, 9, 18, ?, 54

Concept/ApproachThe pattern alternates: multiply by 2, then by 1.5 (i.e., 3/2).

Step-by-step1 × 2 = 22 × 1.5 = 33 × 2 = 66 × 1.5 = 99 × 2 = 1818 × 1.5 = 2727 × 2 = 54 (checks next term)
