Correct option is B
Given:
1, 2, 6, 24, 120, ?
Logic:The factorial of a number n (denoted as n!) is the product of all positive integers from 1 to n.
1 can be written as 1! (since 1! = 1).
2 can be written as 2! (since 2! = 2 × 1 = 2).
6 can be written as 3! (since 3! = 3 × 2 × 1 = 6).
24 can be written as 4! (since 4! = 4 × 3 × 2 × 1 = 24).
120 can be written as 5! (since 5! = 5 × 4 × 3 × 2 × 1 = 120).
2 can be written as 2! (since 2! = 2 × 1 = 2).
6 can be written as 3! (since 3! = 3 × 2 × 1 = 6).
24 can be written as 4! (since 4! = 4 × 3 × 2 × 1 = 24).
120 can be written as 5! (since 5! = 5 × 4 × 3 × 2 × 1 = 120).
6! = 6 × 5 × 4 × 3 × 2 × 1 =720
So, The missing number is 720.
Thus, the correct answer is (b).
