What is the value of ‘X’ in the sequence 2, 7, 22, 67, 202, X, 1822?
(a) 603
(b) 605
(c) 607
(d) 608
Answer :-
The given sequence is 2, 7, 22, 67, 202, X, 1822
The pattern being followed here is given below:
2 × 3 + 1 = 7
7 × 3 + 1 = 22
22 × 3 + 1 = 67
67 × 3 + 1 = 202
202 × 3 + 1 = 607
607 × 3 + 1 = 1822
Hence, option (c) is the correct answer
I have solved it here in easy way while explaining the logic behind it.
