Home » Aptitude » Sequences and Series » Question

The wrong (misfit) number of the sequence 5, 15, 45, 135, 395, 1215, 3645 is :

1. 395
2. 135
3. 45
4. 5

Correct Option: A

The pattern of the sequence is :

15 × 3 = 45
45 × 3 = 135
135 × 3 = 405 ≠ 395 , Since 395 is wrong number . So , 405 is correct number .
405 × 3 = 1215
Thus , option A is required answer .
