Detailed Solution
Download Solution PDFThe pattern followed in the given series is:
[Second term × (Second term - 1) × 3] + 1 = First term
Now we apply the pattern on the given series:
91 : 6 :: ? : 7 :: 169 : 8
[6 × (6 - 1) × 3] + 1 = 91
[6 × 5 × 3] + 1 = 91
90 + 1 = 91
91 = 91
91 : 6 :: ? : 7 :: 169 : 8
[8 × (8 - 1) × 3] + 1 = 169
[8 × 7 × 3] + 1 = 169
168 + 1 = 169
169 = 169
91 : 6 :: ? : 7 :: 169 : 8
[7 × (7 - 1) × 3] + 1 = ?
[7 × 6 × 3] + 1 = ?
126 + 1 = ?
127 = Answer
Hence, the correct answer is "option (3)".
