Some letters are missing from the series. From the given alternative choose the best option which follow the pattern of the series:
p _ r _ _ r s _ r _ p q
Show answer & explanation
Correct answer: A
Explanation
Series: p _ r _ _ r s _ r _ p q
Break the sequence into segments (as group of 4 letters)
Break it like this:
First segment: p_r_
Second segment: _rs_
Third segment: r_pq
Now notice the pattern:
a repeating pattern of p q r s with some symmetry.
Missing letters= q s q p s
Hence, correct answer is option (A).
