1. The problem is to find the missing numbers in each sequence. 2. We analyze each sequence to identify the pattern or rule. 3. Sequence 1: 2, 3, 5, 8, 12, [ ], 23, 30. - Differences: 3-2=1, 5-3=2, 8-5=3, 12-8=4, next difference should be 5. - Missing number = 12 + 5 = 17. 4. Sequence 2: 93, 89, [ ], , 81, 77, 73. - Differences: 89-93 = -4, so subtract 4 each time. - Missing number = 89 - 4 = 85. 5. Sequence 3: 2, 3, 5, 6, 8, 9, 11, 12, [ ] 15, 17, 18. - Pattern alternates between adding 1 and 2. - After 12, add 3 to get 15. - Missing number = 14 (since 12 + 2 = 14, but 14 is missing, so likely 14). 6. Sequence 4: 5, 15, 25, 35, [ 45 ], 55, 65. - Increments of 10. - Missing number is 45 (already given). 7. Sequence 5: 7, 14, 21, [ ], 35, 42. - Increments of 7. - Missing number = 21 + 7 = 28. 8. Sequence 6: 1, 6, 11, 16, [ ], 26. - Increments of 5. - Missing number = 16 + 5 = 21. 9. Sequence 7: 32, 16, 8, [ ], 2, 1. - Dividing by 2 each time. - Missing number = 8 / 2 = 4. Final answers: 1. 17 2. 85 3. 14 4. 45 5. 28 6. 21 7. 4
