Final answer:
To find the missing number in the given sequence, subtract 7 from the previous term.
Step-by-step explanation:
The given sequence is: 100, 93, 84, 73, __, 45.
To find the missing number, we observe that each number in the sequence is decreasing by a certain pattern. The difference between consecutive terms is decreasing by 7 each time.
So, the missing number can be found by subtracting 7 from the previous term: 73 - 7 = 66.
