    Answer: (b) 454

    Solution:-
    1 x 3 + 1 = 3 + 1
    = 4,
    4 x 3 + 1 x 2 = 12 + 2
    = 14,
    14 x 3 + 2 x 2 = 42 + 4
    = 46,
    46 x 3 + 4 x 2 = 138 + 8
    = 146 ,

    Same as,
    146 x 3 + 8 x 2 = 438 + 16
    = 454

    Then, the next number will be 454.

    Hence, the correct answer is option (b) 454.
