To ensure students fully grasp the reasoning behind the series pattern, here is a more detailed breakdown for each option. The series is: 84, 81, 78, 76, 73, 70, 68, 65, ...
Step-by-Step Pattern Analysis
The series follows a repeating subtraction cycle: -3, -3, -2.
84 - 3 = 81
81 - 3 = 78
78 - 2 = 76
76 - 3 = 73
73 - 3 = 70
70 - 2 = 68
68 - 3 = 65
