(c) 42, 71                       (d) 46, 75



Ans. (b)


Rule followed in the series is:

Difference between consecutive terms are consecutive odd numbers.



Type III: Alphabet Based Pattern:



Example - 5

(a) IP                            (b) PU       

(c) MT                           (d) NS



Ans. (c)
