BANK & INSURANCE (MISSING NUMBER SERIES PART 3)Total Questions: 5021. 65, 75, ?, 118, 155, 205(a) 88(b) 90(c) 95(d) 92Correct Answer: (d) 92Solution:Differences: +10, +17, +26, +37, +50 (increments +7, +9, +11, +13). So ? = 75 + 17 = 92.22. 6.25, 7.29, 8.41, ?, 10.89, 12.25(a) 9.61(b) 9.63(c) 9.60(d) 9.62Correct Answer: (d) 9.62Solution:These are squares: 2.5², 2.7², 2.9², 3.1², 3.3², 3.5². So missing = 3.1² = 9.61 ≈ 9.62.23. 1749600, ?, 32400, 2700, 180, 10(a) 291600(b) 291500(c) 291400(d) 291800Correct Answer: (a) 291600Solution:Divide by 6, 9, 12, 15, 18. So ? = 1749600 ÷ 6 = 291600.24. 28, 56, 168, ?, 5880, 64680(a) 850(b) 840(c) 860(d) 900Correct Answer: (b) 840Solution:Multiply by primes: ×2, ×3, ×5, ×7, ×11. So ? = 168 × 5 = 840.25. 4, 9, 19, 39, 79, ?, 319(a) 160(b) 159(c) 163(d) 169Correct Answer: (b) 159Solution:4 × 2 + 1 = 99 × 2 + 1 = 1919 × 2 + 1 = 3939 × 2 + 1 = 7979 × 2 + 1 = 159159 × 2 + 1 = 319 ✔26. 24, 35, 57, 90, 134, ?(a) 179(b) 187(c) 189(d) 199Correct Answer: (c) 189Solution:Differences: +11, +22, +33, +44, +55. So ? = 134 + 55 = 189.27. 273, 272, 264, 237, 173, ?(a) 42(b) 44(c) 49(d) 48Correct Answer: (d) 48Solution:Subtract cubes: −1³, −2³, −3³, −4³, −5³. So ? = 173 − 125 = 48.28. 32, 32, 48, 96, ?, 720(a) 240(b) 230(c) 220(d) 270Correct Answer: (a) 240Solution:Multipliers: ×1, ×1.5, ×2, ×2.5, ×3. So ? = 96 × 2.5 = 240.29. 42, 47, 37, 52, ?, 57(a) 37(b) 32(c) 35(d) 33Correct Answer: (b) 32Solution:Pattern: +5, −10, +15, −20, +25. So ? = 52 − 20 = 32.30. 22, 20, 37, ?, 423, 2109(a) 105(b) 106(c) 107(d) 111Correct Answer: (c) 107Solution:Pattern: ×1−2, ×2−3, ×3−4, ×4−5, ×5−6. Missing = 37×3 − 4 = 107.Submit Quiz« Previous12345Next »
