Question

Which number replaces the question mark? \[ 3, 6, 18, 72, ?, 432 \]

• A. 360
• B. 144
• C. 288
• D. 216

Hint:

Look for a consistent multiplication or division pattern in number sequences to identify missing terms.

Answer 1

The Correct Option is D

The given sequence is:
\[ 3, 6, 18, 72, ?, 432 \]
To find the pattern, we observe the multiplication between consecutive numbers:
- \( 3 \times 2 = 6 \)
- \( 6 \times 3 = 18 \)
- \( 18 \times 4 = 72 \)
Following this pattern, the next number is:
\[ 72 \times 5 = 360 \]
However, the next step is the last term, 432, which is obtained by:
\[ 360 \times 6 = 432 \]
Thus, the correct missing number in the sequence is \( 360 \), which corresponds to option (d).
