Answer: 1560
Explanation 13 × 2 = 26 26 × 3 = 78 78 × 4 = 312 312 × 5 = 1560
Answer: 28
Explanation The pattern in the series is as follows: 9 + 1 = 10 10 + 3 = 13 13 + 6 = 19 The next difference should be +9: 19 + 9 = 28 So, the correct answer is 28 .
Answer: 369
Explanation Multiply the given number by 3, After multiply subtracts 9 from the same number: 6*3=18-9= 9 9*3=27-9= 18 18*3=54-9= 45 45*3=135-9= 126 126*3=378-9= 369
Answer: 20 years
Explanation Let the present ages of son and father be x and (60 -x) years respectively. Then, (60 - x) - 6 = 5(x - 6) 54 - x = 5x - 30 6x = 84 x = 14. Son's age after 6 years = (x+ 6) = 20 years
Answer: 50
Explanation That makes it 4 x 20 to get the total sum which is 80 80=5+10+15+x 80–30=x 50=x
Answer: GJ
Explanation We are given a letter pair sequence: AD, DF, EH, ? First letters: - A → D (+3) - D → E (+1) - E → G (+2) So the pattern in first letters is: +3, +1, +2 Second letters: - D → F (+2) - F → H (+2) - H → J (+2) So the pattern in the second letters is consistently +2 Therefore, the missing pair is: GJ
Answer: 96
Explanation Step 1: Check pattern This looks like factorial series: 1! = 1 ✅ 2! = 2 ✅ 3! = 6 ✅ 4! = 24 ✅ 5! = 120 ❌ 6! = 720 ✅ Notice 96 is in the series instead of 120 .
Answer: 37
Explanation We'll look at the differences between terms: 5 − 2 = 3 10 − 5 = 5 17 − 10 = 7 26 − 17 = 9 So the differences are: 3, 5, 7, 9 → increasing by 2 each time (an arithmetic sequence). The next difference should be: 11 Now add 11 to the last term: 26 + 11 = 37
Answer: 34
Explanation 8 , 22, 8 , 28, 8 , 34, 8, 40, 8, 46, 8 , 52, 8, 58, 8 , 62, 8 , -------- Now add 6 with 22 or 28. 22 + 6 = 28 28 + 6 = 34. So the answer is d = 34. ****** ND11-12-2022
Answer: 60
Explanation The pattern in the series is: +2, ×2, +2, ×2, +2... Applying the pattern: 4 + 2 = 6 6 × 2 = 12 12 + 2 = 14 14 × 2 = 28 28 + 2 = 30 30 × 2 = 60
