Correct Option: B
The given sequence is based on the following pattern :
First term = 27
Second term = First term ÷ 3 = 27 ÷ 3 = 9
Third term = Second term ÷ 3 = 9 ÷ 3 = 3
Fourth term = Third term ÷ 3 = 3 ÷ 3 = ?
∴ ? = 1
| Fifth term = Fourth term ÷ 3 = | |
| 3 |
| Sixth term = Fifth term × | = | ||
| 3 | 9 |
........... and so on.
Hence , The value of ? is 1.
