BANK & INSURANCE (MISSING NUMBER SERIES PART 1)Total Questions: 5041. 32, 38, ?, 86, 128, 182(a) 56(b) 54(c) 58(d) 52Correct Answer: (a) 56Solution:Differences: +6, +18, +30, +42, +54 (increase by 12). So ? = 38 + 18 = 56.42. 23, 40, 60, 89, 145, ?(a) 278(b) 282(c) 280(d) 284Correct Answer: (b) 282Solution:Differences: +17, +20, +29, +56. The extra added each time: +3, +9, +27 (×3). Next +81 ⇒ next difference = 56 + 81 = 137. So ? = 145 + 137 = 282.43. 8, 12, 21, 46, 95, ?(a) 196(b) 212(c) 216(d) 218Correct Answer: (c) 216Solution:Differences: +4, +9, +25, +49 = 2², 3², 5², 7² (squares of consecutive primes). Next difference = 11² = 121. So ? = 95 + 121 = 216.44. 42, 54, 69, 85, 100, ?(a) 108(b) 110(c) 116(d) 112Correct Answer: (d) 112Solution:Let's analyze:42 + 12 = 5454 + 15 = 6969 + 16 = 8585 + 15 = 100100 + 12 = 112Pattern: Alternating additions (12, 15, 16, 15, 12) - seems like increasing then decreasingSo, next: 11245. 7, 4, 5, 9, 20, ?(a) 45.5(b) 52.5(c) 48.5(d) 55.5Correct Answer: (b) 52.5Solution:Pattern: ×0.5 + 0.5; ×1 + 1; ×1.5 + 1.5; ×2 + 2 (multiplier and addend increase by 0.5). Next is ×2.5 + 2.5 ⇒ 20×2.5 + 2.5 = 52.5.46. 24, 43, 81, 138, ?, 309(a) 212(b) 216(c) 214(d) 210Correct Answer: (c) 214Solution:Differences: +19, +38, +57, +76, +95 = 19×1, 19×2, 19×3, 19×4, 19×5. So missing = 138 + 76 = 214.47. 525, 524, 516, 489, ?, 300(a) 435(b) 415(c) 420(d) 425Correct Answer: (d) 425Solution:Subtract cubes: −1³, −2³, −3³, −4³, −5³. So missing = 489 − 64 = 425 (and 425 − 125 = 300).48. 24, 36, 72, 180, ?, 1890(a) 540(b) 575(c) 520(d) 625Correct Answer: (a) 540Solution:Multiply by increasing 0.5 steps: ×1.5, ×2, ×2.5, ×3, ×3.5. So missing = 180 × 3 = 540.49. 32, 37, 27, 42, ?, 47(a) 18(b) 22(c) 20(d) 24Correct Answer: (b) 22Solution:Pattern: +5, −10, +15, −20, +25. So missing = 42 − 20 = 22.50. 12, 10, 17, 47, ?, 909(a) 181(b) 178(c) 183(d) 185Correct Answer: (c) 183Solution:Pattern: ×1−2, ×2−3, ×3−4, ×4−5, ×5−6. Missing = 47×4 − 5 = 183 (and 183×5 − 6 = 909).Submit Quiz« Previous12345
