HEC HAT-4 (Biological / Medical / Physical Sciences) analytical reasoning Letter & Symbol Series Set 2

HEC HAT-4 (Biological / Medical / Physical Sciences) analytical reasoning Letter & Symbol Series — Set 2

Question 1
Q1. A letter series is: B, D, F, H. What is the next letter?
- A) J
- B) I
- C) K
- D) L
Answer: J
Explanation: The series is incrementing by 2 letters, so the next letter is J. I is incorrect as it doesn't follow the increment pattern.
Question 2
Q2. Identify the next symbol in the series: $, #, @, !. If the pattern reverses, what comes next?
- A) @
- B) #
- C) $
- D) !
Answer: $
Explanation: The series is reversing its initial sequence, so the next symbol is $. # is tempting but incorrect as it's not the next in reverse.
Question 3
Q3. In the series: A, Z, B, Y, C, X. What comes next?
- A) D, W
- B) C, W
- C) D, Y
- D) E, V
Answer: D, W
Explanation: The pattern alternates between alphabet start and end, incrementing/decrementing accordingly, so D, W follows. C, W is incorrect due to not following the correct sequence.
Question 4
Q4. The series is: 1st letter, 2nd last letter, 2nd letter, 3rd last letter. What comes next?
- A) 3rd letter, 4th last letter
- B) 4th letter, 3rd last letter
- C) 3rd letter, 5th last letter
- D) 5th letter, 2nd last letter
Answer: 3rd letter, 4th last letter
Explanation: The pattern alternates between the start and end of the alphabet, incrementing/decrementing positions, so 3rd letter, 4th last letter is correct. 4th letter is incorrect as it doesn't follow the sequence.
Question 5
Q5. Given the series: F, G, H, I, J. What comes next?
- A) K
- B) L
- C) M
- D) N
Answer: K
Explanation: The series is incrementing alphabet letters, so K is the next letter. L is tempting but not the immediate next.
Question 6
Q6. A symbol series is given: *, *, ^, ^, &. What comes next?
- A) &, &
- B) %
- C) ^
- D) *
Answer: &, &
Explanation: The pattern repeats the symbol twice before moving to the next, so &, & follows. % is incorrect as it's not the next symbol in sequence.
Question 7
Q7. In the alphabet, if the 1st letter is paired with the last, 2nd with 2nd last, what is the 3rd pair?
- A) C, X
- B) C, Y
- C) D, X
- D) C, Z
Answer: C, Y
Explanation: The 3rd letter is 'C' and the 3rd last letter is 'Y', so C, Y is the correct pair. C, X is tempting but incorrect.
Question 8
Q8. The given series is: A, E, I, M. What comes next?
- A) Q
- B) R
- C) S
- D) T
Answer: Q
Explanation: The pattern is adding 4 letters, so the next letter is Q. R is incorrect as it doesn't follow the pattern.
Question 9
Q9. A series of symbols is given: !, @, #, $. If the pattern is repeating, what comes next?
- A) !
- B) @
- C) #
- D) $
Answer: !
Explanation: The pattern repeats the sequence, so ! comes next. @ is tempting but not the start of the repeat sequence.
Question 10
Q10. In a letter series: Z, X, V, T. What comes next?
- A) R
- B) S
- C) Q
- D) P
Answer: R
Explanation: The pattern is decrementing by 2 letters, so R comes next. S is incorrect as it doesn't follow the decrement pattern.
Question 11
Q11. The series given is: 2nd letter, 4th letter, 6th letter. What is the next letter?
- A) 8th letter
- B) 7th letter
- C) 5th letter
- D) 9th letter
Answer: 8th letter
Explanation: The pattern increments by 2 letters, so the 8th letter comes next. 7th letter is incorrect as it doesn't follow the increment.
Question 12
Q12. In the series: *, ^, &, *. What comes next?
- A) ^
- B) &
- C) *
- D) %
Answer: ^
Explanation: The pattern is repeating the initial sequence, so ^ comes next. & is tempting but not the next in the sequence.
Question 13
Q13. A letter series is: E, J, O, T. What comes next?
- A) Y
- B) X
- C) W
- D) Z
Answer: Y
Explanation: The pattern is incrementing by 5 letters, so Y comes next. X is incorrect as it doesn't follow the pattern.
Question 14
Q14. The given symbol series is: %, ^, &, *. If it alternates and reverses, what comes next?
- A) %
- B) ^
- C) &
- D) *
Answer: ^
Explanation: The series alternates and reverses, so ^ comes next. % is tempting but not the correct next symbol.
Question 15
Q15. In the alphabet series: D, G, J, M. What is the next letter?
- A) P
- B) O
- C) N
- D) Q
Answer: P
Explanation: The pattern increments by 3 letters, so P is the next letter. O is incorrect as it doesn't follow the pattern.
Question 16
Q16. A series is given as: A1, B2, C3, D4. What comes next?
- A) E5
- B) E4
- C) D5
- D) F5
Answer: E5
Explanation: The pattern combines alphabet increment with number increment, so E5 is next. E4 is incorrect due to not following the number sequence.
Question 17
Q17. The letter series is: T, Q, N, K. What comes next?
- A) H
- B) J
- C) I
- D) G
Answer: H
Explanation: The pattern decrements by 3, 3, 3, so H comes next. J is incorrect as it doesn't follow the decrement pattern.
Question 18
Q18. In the symbol series: ~, !, @, #. What comes next if following a keyboard sequence?
- A) $
- B) %
- C) ^
- D) &
Answer: $
Explanation: The pattern follows a keyboard sequence, so $ is the next symbol. % is tempting but not the correct next symbol.
Question 19
Q19. A series begins with the letters C, H, M, R. The next letter is determined by skipping three letters. What is the correct next letter?
- A) T
- B) V
- C) U
- D) W
Answer: U
Explanation: Letters increase by 5 (C→H→M→R→U). U is correct because it matches what the question requires. USAT, HAT and MDCAT analytical sections repeat this pattern.
Question 20
Q20. In the sequence A, Z, B, Y, C, X, the next pair is likely to be ___.
- A) D, W
- B) D, V
- C) E, W
- D) E, V
Answer: D, W
Explanation: Alternating forward (A→B→C) and reverse (Z→Y→X) sequences. Option C ignores reverse pattern.
