In the letter series, some of the letters are missing, which are given in the alternatives (A), (B), (C) and (D).
m n o n o p q o p q r _ _ _ _ s t u
(A) r
(B) s
(C) q
(D) p
Choose the correct sequence from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (B), (D), (C), (A)
The series is made of groups of consecutive letters: each group starts one letter later and is one letter longer than the one before.
m n o — 3 letters, from m
n o p q — 4 letters, from n
o p q r s — 5 letters, from o
p q r s t u — 6 letters, from p
The four blanks are therefore s, p, q, r, that is, (B), (D), (C), (A).
