Answer is Wrong!
Answer is Right!
The answer is 6.
The missing number is the number that completes the sequence. The sequence is a series of numbers that are each one less than the previous number. Starting with 9, the sequence goes 9, 8, 7, 6, 5, 4, 3, 2, 1.
Option A, 9, is not the missing number because it is not one less than the previous number in the sequence.
Option B, 7, is not the missing number because it is not one less than the previous number in the sequence.
Option C, 1, is not the missing number because it is not one less than the previous number in the sequence.
Option D, 6, is the missing number because it is one less than the previous number in the sequence.
