    1. Answer:  (c) 183

    Explanation:-

    (1)² + 2= 3
    (3)² +4 = 13
    (5)² +6 = 31
    (7)² +8 =57
    (9)² +10 =91
    (11)² +12 = 133
    so, (13)² + 14 =183

    Then, the next number is (c) 183, 

    Hence, the correct answer is option (c) 183. 

    2.  Answer: (b) 1728 

    Explanation:- 
    8 x 2 = 16,  16 x 3 = 48,   48 x 2 = 96,    96 x 3 = 288,   288 x 2 = 576, 
    Same as,  576 x 3 = 1728

    Then, the next number is 1728. 

    Hence, the correct answer is option (b) 1728.
