Final answer:
The missing number in the sequence is 0. The sequence follows a pattern of dividing each number by 2 to get the next number.
Step-by-step explanation:
The missing number in the sequence is 0.
This sequence is a descending order sequence, where each number is divided by 2 to get the next number.
Starting with 8, when we divide it by 2 we get 4, then 4 divided by 2 gives us 2, 2 divided by 2 gives us 1, and finally 1 divided by 2 gives us 0.
