    1. (B) 90

      Explanation:-
      20 + 12 = 32,  32 + 13 = 45, 45 + 14 = 59,  59 + 15 = 74,   Same as,   74 + 16 = 90.

      Then, the next term is 90. 

      Hence, the correct answer is option (B) 90. 

    2.  (C) 85

      Explanation:-
      210 – 15 = 195,  195 – (15 + 5) = 195 – 20
       = 175, 
      175 – (20 + 5) 
       = 175 – 25
       = 150, 
      150 – (25 + 5)
       = 150 – 30
       = 120, 
      120 – (30 + 5)
       = 120 – 35
       = 85, 

      Then, the next next term is 85. 

      Hence, the correct answer is option (C) 85. 

    3.  (A) 52

      Explanation:-
      3 + 2 = 5  & 5 x 2 = 10,  10  + 2 = 12  &  12 x 2 = 24,   24 + 2 = 26  & 26 x 2 = 52.

      Then, the next term is 52. 

      Hence, the correct answer is option (A) 52.  

    4.  (B) 48 

      Explanation:-
      3 + 5 = 8,  8 + (5 + 2)  = 8 + 7 => 15, 
      15 + (7 + 2) => 15 + 9 = 24, 
      24 + (9 + 2) = 24 + 11 => 35, 
      35 + (11 + 2) = 35 + 13 => 48.

      Then, the next term is 48. 

      Hence, the correct answer is option (B) 48. 

    5.  (D) 445

      Explanation:-
      5 x 3 + 1 = 15 + 1 
       = 16, 
      16 x 3 + 1 = 48 + 1
       = 49, 
      49 x 3 + 1 = 147 + 1
       = 148, 
      148 x 3 + 1 = 444 + 1
       = 445.

      Then, the next term is 445. 

      Hence, the correct answer is option (D) 445.
