A series is given with one term missing. Select the correct alternative from the given ones that will complete the series.
TGA, WDD, __, CXJ, FUM
Show answer & explanation
Correct answer: A
Explanation
Given Series: TGA, WDD, ___, CXJ, FUM
The first letters are:
T (20), W (23), ?, C (3), F (6) — Positions in the alphabet.
From T (20) to W (23): +3
From W (23) to ?: +3 → 26 (Z)
From Z (26) to C (3): +3 (Wrapping around the alphabet)
From C (3) to F (6): +3
Therefore, the missing first letter is Z.
The second letters are:
G (7), D (4), ?, X (24), U (21)
From G (7) to D (4): -3
From D (4) to ?: -3 → 1 (A)
From A (1) to X (24): -3 (Wrapping around the alphabet)
From X (24) to U (21): -3
Therefore, the missing second letter is A.
The third letters are:
A (1), D (4), ?, J (10), M (13)
From A (1) to D (4): +3
From D (4) to ?: +3 → 7 (G)
From G (7) to J (10): +3
From J (10) to M (13): +3
Therefore, the missing third letter is G.
Therefore, the missing term is ZAG.
Hence, the correct answer is Option (1).
