To solve this question, we need to identify the pattern or relationship between the given numbers.
If we look closely, we can see that each number is obtained by multiplying the previous number by a specific factor. Let's find this factor:
6 = 3 * 2
18 = 6 * 3
72 = 18 * 4
360 = 72 * 5
So, we can observe that each number is obtained by multiplying the previous number by the next consecutive positive integer.
Now, let's find the next number in the sequence:
360 * 6 = 2160
Therefore, the missing number in the sequence is 2160.
The correct answer is A) 2160.
