The Correct Option is A
Solution and Explanation
Concept:
Observe patterns separately in numbers and letters:
Step 1: Analyze the letters.
\[ K,\ M,\ Q,\ ?,\ W \] Positions in alphabet: \[ K(11),\ M(13),\ Q(17),\ ?,\ W(23) \] Pattern: \[ +2,\ +4,\ +2,\ +4 \] So, \[ Q(17) + 2 = S(19) \]
Step 2: Analyze the last numbers.
\[ 1,\ 3,\ 7,\ ?,\ 3 \] Pattern: \[ \times 2 + 1 \] \[ 1 \rightarrow 3 \rightarrow 7 \rightarrow 15 \] So missing number = 15 → last digit = 9
Step 3: Analyze the first numbers.
\[ 1,\ 1,\ 1,\ ?,\ 2 \] Pattern: stays 1 for first four terms, then becomes 2. So missing first number = 1. Final term: \[ 1S9 \]
Hence, the correct answer is (A).
- First number
- Middle letter
- Last number
Step 1: Analyze the letters.
\[ K,\ M,\ Q,\ ?,\ W \] Positions in alphabet: \[ K(11),\ M(13),\ Q(17),\ ?,\ W(23) \] Pattern: \[ +2,\ +4,\ +2,\ +4 \] So, \[ Q(17) + 2 = S(19) \]
Step 2: Analyze the last numbers.
\[ 1,\ 3,\ 7,\ ?,\ 3 \] Pattern: \[ \times 2 + 1 \] \[ 1 \rightarrow 3 \rightarrow 7 \rightarrow 15 \] So missing number = 15 → last digit = 9
Step 3: Analyze the first numbers.
\[ 1,\ 1,\ 1,\ ?,\ 2 \] Pattern: stays 1 for first four terms, then becomes 2. So missing first number = 1. Final term: \[ 1S9 \]
Hence, the correct answer is (A).
