Question

Which number will replace the question mark?
3, 6, 18, 72, ?

• A. 144
• B. 360
• C. 288
• D. 216

Hint:

Check for multiplication or exponential patterns in consecutive terms of a number series before trying complex logic.

Answer 1

The Correct Option is B

Step 1: Observe the given sequence:
3, 6, 18, 72, ?

Step 2: Identify the pattern:
3 × 2 = 6
6 × 3 = 18
18 × 4 = 72

Step 3: Continue the pattern:
The multipliers are increasing consecutively: 2, 3, 4, so next is 5.

Step 4: Find the next term:
72 × 5 = 360

Step 5: Conclusion:
The missing number is 360.

Final Answer: 360
