So ? = 200×4 + 9 = 809.12. ?, 17, 35, 71, 143, 287(a) 6(b) 5(c) 8(d) 9Correct Answer: (c) 8Solution:Pattern: ×2 + 1. So first term = (17 − 1)/2 = 8.13. 15, ?, 54, 170, 688, 3448(a) 21(b) 22(c) 25(d) 23Correct Answer: (d) 23Solution:Pattern: ×1+8, ×2+8, ×3+8, ×4+8, ×5+8. So ? = 15×1 + 8 = 23.14. 133, 157, 183, 211, ?, 273(a) 241(b) 231(c) 237(d) 247Correct Answer: (a) 241Solution:Differences: +24, +26, +28, +30, +32. So ? = 211 + 30 = 241.15. 250, 648, 686, 1536, 1458, ?(a) 2995(b) 3000(c) 3010(d) 3118Correct Answer: (b) 3000Solution:Two interleaved patterns: 250=2×5³, 686=2×7³, 1458=2×9³; and 648=3×6³, 1536=3×8³, so next = 3×10³ = 3000.16. 50, 52, ?, 70, 90, 120(a) 54(b) 55(c) 58(d) 60Correct Answer: (c) 58Solution:Differences: +2, +6, +12, +20, +30 (increments +4, +6, +8, +10). So ? = 52 + 6 = 58.17. 38, 58, ?, 158, 238, 338(a) 88(b) 108(c) 118(d) 98Correct Answer: (d) 98Solution:Differences: +20, +40, +60, +80, +100. So ? = 58 + 40 = 98.18. 9, 36, 144, 441, ?, 2304(a) 1089(b) 1088(c) 1044(d) 1099Correct Answer: (a) 1089Solution:Squares of: 3, 6, 12, 21, 33, 48 (increments +3, +6, +9, +12, +15). So missing = 33² = 1089.19. 81, 361, 841, 1521, 2401, ?(a) 3471(b) 3481(c) 3381(d) 3581Correct Answer: (b) 3481Solution:These are squares: 9², 19², 29², 39², 49². Next is 59² = 3481.20. 5, 10, 30, ?, 600, 3600(a) 110(b) 130(c) 120(d) 115Correct Answer: (c) 120Solution:Multiply by 2, 3, 4, 5, 6. So ? = 30 × 4 = 120.Submit Quiz« Previous12345Next »
