Next +9.6 ⇒ missing = 35.7 + 9.6 = 45.3.42. 7, 7, 21, 105, 735, ?(a) 6616(b) 6617(c) 6611(d) 6615Correct Answer: (d) 6615Solution:Multiply by odd numbers: ×1, ×3, ×5, ×7, ×9. Missing = 735 × 9 = 6615.43. 6, 12, 36, ?, 720, 4320(a) 144(b) 142(c) 146(d) 154Correct Answer: (a) 144Solution:Pattern: ×2, ×3, ×4, ×5, ×6. Missing = 36 × 4 = 144.44. 42, 52, 72, 112, 192, ?(a) 348(b) 356(c) 352(d) 362Correct Answer: (c) 352Solution:Differences: +10, +20, +40, +80, +160. Missing = 192 + 160 = 352.45. 60, 150, ?, 450, 450, 225(a) 250(b) 350(C) 200(d) 300Correct Answer: (d) 300Solution:Multipliers: ×2.5, ×2, ×1.5, ×1, ×0.5. Missing = 150 × 2 = 300.46. 10, 135, ?, 226, 234, 235(a) 199(b) 189(c) 196(d) 195Correct Answer: (a) 199Solution:Differences are decreasing cubes: +125, +64, +27, +8, +1 (5³,4³,3³,2³,1³). So ? = 135 + 64 = 199.47. 11, 13, 19, ?, 51, 81(a) 33(b) 31(c) 37(d) 30Correct Answer: (b) 31Solution:Differences: +2, +6, +12, +20, +30 where each is n(n+1): 1·2, 2·3, 3·4, 4·5, 5·6. So ? = 19 + 12 = 31.48. 1.5, 1.5, 3, 12, 96, ?(a) 1540(b) 1596(c) 1536(d) 1636Correct Answer: (c) 1536Solution:Multiply by 1, 2, 4, 8, 16. So ? = 96 × 16 = 1536.49. 15, 40, 56, ?, 69, 70(a) 60(b) 66(c) 62(d) 65Correct Answer: (d) 65Solution:Add squares: +25, +16, +9, +4, +1. So ? = 56 + 9 = 65.50. 124, 131, 142, 155, ?, 191(a) 172(b) 171(c) 176(d) 173Correct Answer: (a) 172Solution:Add consecutive primes: +7, +11, +13, +17, +19. So ? = 155 + 17 = 172.Submit Quiz« Previous12345
