    1. (c) 51

      Explanation:-
      16 + 2 x 7 = 16 + 14
       = 30, 
      30 + 3 x 7 = 30 + 21
       = 51, 
      51 + 4 x 7 = 51 + 28
       = 79, 
      79 + 5 x 7 = 79 + 35
       = 114

      Then, the missing number is 51. 

      Hence, the correct answer is option (c) 51. 

    2. (c) 8

      Explanation:-

    3. (c) L

      Explanation:-

      T – 2 = R, R – 2 = P,  P – 2 = N same as,  N – 2 = L

      Then, the next letter will be L. 

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

    4. (d) 9

      Explanation:-
      4 x 2 + 1 = 8 + 1
      = 9, 
      9 x 2 + 1 = 18 + 1
       = 19, 
      19 x 2 + 1 = 38 + 1
      39, 
      39 x 2 + 1 = 78 + 1
       = 79, 

      Then, the missing number will be 9. 

      Hence, the correct answer is option (d) 9. 

    5. (d) P 

      Explanation:-
      Z – 2 = X,  X – 2 = V, V – 2 = T,  T – 2 = R,  R – 2 = P,  P – 2 = N. 

      Then, the missing letter will be P.

      Hence, the correct answer is (d) P.
