Find the missing term of the following series:
DCXW, HGTS, ........., POLK, TSHG
The pattern in this series is found by treating the letter positions in each four-letter group as four independent arithmetic sequences.
4 (D), 8 (H), ?, 16 (P), 20 (T)8 + 4 = 12, which corresponds to the letter L.3 (C), 7 (G), ?, 15 (O), 19 (S)7 + 4 = 11, which corresponds to the letter K.24 (X), 20 (T), ?, 12 (L), 8 (H)20 - 4 = 16, which corresponds to the letter P.23 (W), 19 (S), ?, 11 (K), 7 (G)19 - 4 = 15, which corresponds to the letter O.
Combining the letters for the missing third term gives us LKPO.
Final Answer: D. LKPO
