The Correct Option is B
Solution and Explanation
Concept:
In letter series, convert letters to their alphabetical positions and look for patterns.
Step 1: Convert letters to positions.
\[ I(9),\ L(12),\ Q(17),\ X(24),\ S(19),\ V(22),\ M(13) \]
Step 2: Split into two alternating sequences.
Odd positions: \[ I(9),\ Q(17),\ S(19),\ M(13) \] Pattern: \[ +8,\ +2,\ -6 \] Even positions: \[ L(12),\ X(24),\ V(22),\ ? \] Pattern: \[ +12,\ -2,\ -16 \] So, \[ V(22) - 16 = 6 \]
Step 3: Convert back to letter.
\[ 6 \rightarrow F \]
Hence, the missing term is F.
