BANK & INSURANCE (MISSING NUMBER SERIES PART 2)Total Questions: 5011. 20, 32, 50, 74, 104, ?(a) 140(b) 135(c) 130(d) 142Correct Answer: (a) 140Solution:Differences: +12, +18, +24, +30 (increase by 6). Next +36 ⇒ ? = 104 + 36 = 140.12. 5, 15, 35, 75, 155, ?(a) 305(b) 315(c) 310(d) 325Correct Answer: (b) 315Solution:Differences: +10, +20, +40, +80 (doubling). Next +160 ⇒ ? = 155 + 160 = 315.13. 13, 15, 18, 23, 30, ?(a) 39(b) 43(c) 41(d) 42Correct Answer: (c) 41Solution:Differences are consecutive primes: +2, +3, +5, +7, next +11 ⇒ ? = 30 + 11 = 41.14. 10, 17, 26, 37, 50, ?(a) 75(b) 62(c) 66(d) 65Correct Answer: (d) 65Solution:Differences: +7, +9, +11, +13 (odd numbers). Next +15 ⇒ ? = 50 + 15 = 65.15. 16, 24, 51, 115, 240, ?(a) 454(b) 456(c) 455(d) 460Correct Answer: (b) 456Solution:Differences: +8, +27, +64, +125 = 2³, 3³, 4³, 5³. Next +6³=216 ⇒ ? = 240 + 216 = 456.16. 124, 43, 115, ?, 106, 61(a) 48(b) 55(c) 52(d) 54Correct Answer: (c) 52Solution:Alternate − and + multiples of 9: −81(9×9), +72(8×9), −63(7×9), +54(6×9), −45(5×9). So ? = 115 − 63 = 52.17. 5000, 1000, 400, 240, 192, ?(a) 190(b) 180(c) 195(d) 192Correct Answer: (d) 192Solution:Multiply by 0.2, 0.4, 0.6, 0.8, 1.0. So next = 192 × 1.0 = 192.18. 7200, 3600, 1200, ?, 60, 10(a) 400(b) 300(c) 200(d) 350Correct Answer: (b) 300Solution:Divide by 2, 3, 4, 5, 6. So ? = 1200 ÷ 4 = 300.19. 36, 16, 80, ?, 300, 280(a) 70(b) 80(c) 60(d) 110Correct Answer: (c) 60Solution:Pattern: −20, ×5, -20, ×5, −20. So ? = 80 - 20 = 60.Answer: 60There can be another way to solve this question as detailed below: (this is only for information)Pattern: −20, ×5, +20, ×3, −20. So ? = 80 + 20 = 100.Answer: 10020. 60, 72, 96, ?, 228, 360(a) 140(b) 142(c) 146(d) 144Correct Answer: (d) 144Solution:Differences: +12, +24, +48, +84, +132. These are 12×(1,2,4,7,11) where increments are +1,+2,+3,+4. So ? = 96 + 48 = 144.Submit Quiz« Previous12345Next »
