Letter & Symbol Series MCQs set 3 for HEC HAT-General (Religious Studies) analytical reasoning — 20 solved questions.
Q1. Given the symbol series @, 2, #, 4, $, 6, the next pair is ___.
Answer: %, 8
Explanation: Symbols progress alphabetically, numbers increment by +2. Option C skips number increment.
Q2. The series K, J, I, H, G follows a reverse alphabetical pattern. What precedes K?
Answer: L
Explanation: Sequence reverses alphabet (L→K→J→I→H→G). L is correct because it matches what the question requires. USAT, HAT and MDCAT analytical sections repeat this pattern.
Q3. In the series D, G, L, Q, the letters progress by increasing intervals. What is the interval after Q?
Answer: +6
Explanation: Intervals: +3, +5, +7. Next is +9 to reach Z. Option A underestimates increment pattern.
Q4. The symbol series *, A, **, B, ***, C continues with ___.
Answer: ****, D
Explanation: Stars increase by one, letters progress forward. ****, D is correct because it matches what the question requires. USAT, HAT and MDCAT analytical sections repeat this pattern.
Q5. The sequence W, T, Q, N follows a consistent backward skip. What is the next letter?
Answer: K
Explanation: Each letter skips +3 backward (W→T→Q→N→K). K is correct because it matches what the question requires. USAT, HAT and MDCAT analytical sections repeat this pattern.
Q6. A series starts with 3, A, 6, B, 9, C. The next pair is ___.
Answer: 12, D
Explanation: Numbers increase by +3, letters progress forward. Option D underestimates number increment.
Q7. In the series M, O, Q, S, the next letter is determined by skipping one letter. Which is correct?
Answer: U
Explanation: Even letters (M→O→Q→S→U). U is correct because it matches what the question requires. USAT, HAT and MDCAT analytical sections repeat this pattern.
Q8. The symbol series &, 5, #, 10, @, 15 continues with ___.
Answer: $, 20
Explanation: Symbols progress alphabetically, numbers increase by +5. Option B skips symbol progression.
Q9. The sequence X, U, R, O follows a consistent backward pattern. What precedes X?
Answer: Z
Explanation: Sequence reverses by +3 (Z→X→U→R→O). Z is correct because it matches what the question requires. USAT, HAT and MDCAT analytical sections repeat this pattern.
Q10. In the series B, D, G, K, the intervals between letters increase by +1. Next letter is ___.
Answer: P
Explanation: Intervals: +2, +3, +4, +5 (B→D→G→K→P). P is correct because it matches what the question requires. USAT, HAT and MDCAT analytical sections repeat this pattern.
Q11. The symbol series !, 1, ?, 2, #, 3 continues with ___.
Answer: $, 4
Explanation: Symbols progress alphabetically, numbers increase by +1. Option C skips symbol progression.
Q12. The series L, F, K, E, J follows a pattern where letters alternate in direction. Next pair is ___.
Answer: D, I
Explanation: Alternates backward (L→F) and forward (F→K→E→J→D→I). D, I is correct because it matches what the question requires. USAT, HAT and MDCAT analytical sections repeat this pattern.
Q13. A sequence starts with 1, A, 3, C, 5, E. The next pair is ___.
Answer: 7, G
Explanation: Odd numbers and even letters progress. Option C mixes letter progression error.
Q14. The letters P, I, R, L, U follow a pattern where vowels and consonants alternate. Next letter is ___.
Answer: O
Explanation: Alternates consonant (P→R→U) and vowel (I→L→O). O is correct because it matches what the question requires. USAT, HAT and MDCAT analytical sections repeat this pattern.
Q15. In the symbol series +, 2, -, 4, ×, 6, the next pair is ___.
Answer: ÷, 8
Explanation: Math symbols in order, numbers increase by +2. USAT, HAT and MDCAT analytical sections repeat this pattern.
Q16. The series Z, S, O, L follows a pattern where each letter skips decreasing intervals. Next is ___.
Answer: I
Explanation: Intervals: -5 (Z→S), -4 (S→O), -3 (O→L), -2 (L→I). Option C overestimates skip.
Q17. The sequence N, G, P, I, R follows a pattern where letters alternate direction. Next letter is ___.
Answer: M
Explanation: Alternates forward (N→P→R) and backward (G→I→M). M is correct because it matches what the question requires. USAT, HAT and MDCAT analytical sections repeat this pattern.
Q18. In the series T, W, Z, C, the letters progress by skipping two letters. Next is ___.
Answer: F
Explanation: Each skips +3 (T→W→Z→C→F). F is correct because it matches what the question requires. USAT, HAT and MDCAT analytical sections repeat this pattern.
Q19. A 16-year-old athlete feels muscle fatigue during a sprint. Which process is responsible for the rapid ATP production in this situation?
Answer: Lactic acid fermentation
Explanation: Lactic acid fermentation is responsible for rapid ATP production in high-intensity, short-duration activities like sprinting. Aerobic respiration and glycolysis are slower processes.
Q20. A patient has a severe case of hypothermia. Which bodily function is most severely impaired due to the decrease in ATP production?
Answer: Circulatory system
Explanation: The circulatory system is most severely impaired due to the decrease in ATP production, leading to decreased heart rate and blood pressure. Nervous, muscular, and respiratory systems are also affected, but to a lesser extent.
