Find the missing number?

9
6
0
1

The answer is 1.

The missing number is the number that completes the pattern. The pattern is a series of numbers that are each 2 less than the number before it. Starting with 9, the numbers in the pattern are 9, 7, 5, 3, 1.

Option A, 9, is not the missing number because it is not in the pattern. Option B, 6, is not the missing number because it is not in the pattern. Option C, 0, is not the missing number because it is not in the pattern. Option D, 1, is the missing number because it is in the pattern.
