Answer: ...85, 79, 72, 64, 55
Step-by-step explanation: The numbers are decreasing sequentially by an increasing amount: 1, 2, 3, 4, and so on. Thus, the next numbers would decrease by their corresponding term number in the sequence.
100 - 0 = 100
100 - 1 = 99
99 - 2 = 97
97 - 3 = 94
94 - 4 = 90
...
90 to 85 is a decrease of 5.
85 to 79 is a decrease of 6.
79 to 72 is a decrease of 7.
72 to 64 is a decrease of 8.
64 to 55 is a decrease of 9.
