    • 13
    • 14
    • 15
    • E. 17 (correct answer)
    Correct answer: D
    This question tests pattern recognition in a number sequence, specifically identifying interleaved arithmetic progressions.
  2. Question 2
    Number series: 1, 1, 2, 3, 5, ?
    • 7
    • 8 (correct answer)
    • 10
    • 9
    Correct answer: B
    Recognize the Fibonacci sequence, a fundamental pattern where each number is the sum of the two preceding ones, crucial for pattern identification in logical reasoning.
  3. Question 3
    If A = 1, B = 2, ..., Z = 26, then what is the value of the code: C + @ + E = ? (Where @ means multiply the numerical values of surrounding letters)
    • 3 + (3×5) = 18 (correct answer)
    • 3 + 5 = 8
    • 3 + (2×5) = 13
    • (3×5) + 5 = 20
    Correct answer: A
    Decode the letter-to-number code by correctly applying the specified operator precedence for multiplication and addition.
  4. Question 4
    Directions: In the following question, a number sequence is given with one term missing. Choose the correct term that will continue the same pattern and replace the question mark in the given sequence.17,20,19,22,21,24,23,?
    • 22
    • 24
    • 26 (correct answer)
    • 2
    Correct answer: C
    This question tests pattern recognition in an alternating arithmetic sequence, requiring students to identify the underlying operations.
  5. Question 5
    In the following question, various terms of an alphabet sequence are given with one or more terms missing as shown by (?). Choose the missing term.BZA, DYC, FXE, ?, JVI
    • HUG
    • HWG (correct answer)
    • UHG
    • WHG
    Correct answer: B
    This question tests pattern recognition in letter sequences, requiring the identification of logical progressions in the positions of letters.
  6. Question 6

    • Faisalabad Electric Supply Company (correct answer)
    • None of above
    Correct answer: C
    This question tests your knowledge of common acronyms, specifically those related to public utility companies in Pakistan, requiring recall of factual information.
  8. Question 8
    If 8 + 4 − 7 = 31, then 7 + 6 = ?
    • 26
    • 30
    • 31
    • 32 (correct answer)
    Correct answer: D
    This question tests pattern recognition and rule derivation in a non-standard mathematical system.
