Step 1 — Write the series clearly:
We are given: GMSY, IOUA, KQWC, ?
We need to find the missing 4-letter term.
Step 2 — Break down each term into its letters:
1st term = G M S Y
2nd term = I O U A
3rd term = K Q W C
4th term = ? ? ? ?
Step 3 — Look at the 1st letters across the terms:
G → I → K → ?
Positions in alphabet: G(7), I(9), K(11).
Pattern: increasing by +2 each step.
So the next letter = M (13th letter).
Thus, 1st letter = M.
Step 4 — Look at the 2nd letters across the terms:
M → O → Q → ?
Positions: M(13), O(15), Q(17).
Again, +2 pattern.
Next letter = S (19th letter).
Thus, 2nd letter = S.
Step 5 — Look at the 3rd letters across the terms:
S → U → W → ?
Positions: S(19), U(21), W(23).
Again, +2 pattern.
Next letter = Y (25th letter).
Thus, 3rd letter = Y.
Step 6 — Look at the 4th letters across the terms:
Y → A → C → ?
Now note: After Z, alphabet wraps to A.
Positions: Y(25), A(1), C(3).
Pattern: +2 each time (Y(25) + 2 = 27 → wrap to 1 = A, then +2 = C).
Next = E (5th letter).
Thus, 4th letter = E.
Step 7 — Combine all letters:
The 4th term is M S Y E.
Final Answer: MSYE (Option A).
