Which number replaces the question mark?
3, 6, 18, 72, ?, 432
Explanation
1. Pattern Identification:
The sequence follows a multiplication pattern where the multiplier itself changes in a specific ratio or the terms are related to the final product.
2. Calculation Steps:
To reach 216, the multiplier for the 4th term must be 3:
-
3×2=6
-
6×3=18
-
18×4=72
-
72×3=216
3. Verification of the Final Term:
If the missing number is 216, let's check the next step to get 432:
4. The Complete Pattern:
The multipliers used are 2,3,4,3,2 (a symmetrical pattern).
-
3×2=6
-
6×3=18
-
18×4=72
-
72×3=216
-
216×2=432
Correct Option: (d)
