- A. 36
- B. 40
- C. 42
- D. 46

Correct answer: 42- A. 30
- B. 36
- C. 48
- D. 60
Explanation: Each term is double the one before it, so the next term is 24 times 2, which is 48.
Correct answer: 48- A. 35
- B. 37
- C. 39
- D. 41
Explanation: The differences are 3, 5, 7 and 9, rising by 2 each time, so the next difference is 11 and the next term is 26 plus 11, which is 37.
Correct answer: 37- A. M
- B. N
- C. O
- D. P
Explanation: The gaps between the letters grow by one each step: A to C skips one letter, C to F skips two, F to J skips three, so the next step skips…

- B. 6
- C. 7
- D. 8
Explanation: Two sequences are interleaved: the terms in the odd positions run 1, 2, 3, 4 and those in the even positions run 4, 5, 6, 7, each rising…
Correct answer: 5- A. 44 people
- B. 56 people
- C. 64 people
- D. 74 people
Explanation: Each figure is double the one before, so the growth is geometric rather than arithmetic and the next term is 32 multiplied by 2, giving…
Correct answer: 64 people- A. D390625
- B. D364748
- C. D390524
- D. D390525
Explanation: Each number is multiplied by 25. 15625 x 25 is 390,625 hence, the answer is D390,625.
Correct answer: D390625- A. K66
- B. L64
- C. M68
- D. N90
Explanation: 16 is added every time to each term and the letters alternate. So after J, K will be skipped and 48+16 is 64 so the answer is L64.
Correct answer: L64- A. D9
- B. D10
- C. D9.5
- D. D45
Explanation: 2.5 is added to each number. 2.5+2.5=5 and 5+2.5=7.5 hence 7.5+2.5=10 and D is 10. So, option B is accurate.
Correct answer: D10- A. NQM
- B. PJI
- C. NIJ
- D. NJI
Explanation: The series can be analyzed by examining the letters in each segment. For the second letter in each term, the pattern follows:K (11) → L…
Correct answer: NIJ- A. 111
- B. 120
- C. 121
- D. 132

- B. 24
- C. -16
- D. 32
Explanation: The sequence 0, 8, ?, 48, 80, 120 involves finding a pattern in the differences between consecutive terms.
Correct answer: 24- A. JHK
- B. LAK
- C. JGK
- D. IGJ
Explanation: Noticing the pattern, we can conclude that the middle letter in each sequence is A.
Correct answer: LAK- A. 52
- B. 56
- C. 96
- D. 128
