In the following question, a series is given and it is followed by the starting point of another series. After this a question is given, you have to complete the second series by applying the same logic as in the first given series, and then you have to answer the question.

8, 9, 13, 22, 38, 63,....
12, a, b, c, d, e,

• 1st series
  
  8+1^2= 9
  9+2^2=13
  13+3^2=22
  22+4^2=38
  38+5^2=63
  
  2nd series
  
  12+1^2=13
  13+2^2=17
  17+3^2=26
  26+4^2=42
  42+5^2=67
  
  12, 13, 17, 26, 42, 67
