In the following questions, which one set of letters/numbers when sequentially placed at the gaps in the given letter series shall complete it?
d_ _ef_ _ _12g_16h_20i_24
Show answer & explanation
Correct answer: C
Explanation
Given Series:
d_ _ef_ _ _12g_16h_20i_24
Split into equal clusters (3–3 number&letters )
d _ _ | e f _ |_ _ 12 | g _ 16 | h _ 20 | i _ 24
Pattern: Each cluster follows a continuous sequence of letters and numbers:
d e → e f → f g→ g h → h i→ i j
So, missing letters are in series:
e , f , g , h , i, j
12 → 16 → 20 → 24 ( +4)
So missing numbers in series are:
8 and 4
Hence, the correct answer is option 3.
