Question

How do you solve? "(n+1)!"

Answer 1

`color(green)((n+1)! = (n+1) * n! = (n+1) * n * (n-1) * (n-2) * . . . * 3 * 2 * 1`

Explanation:

To get the factorial of a number n the given formula is used, n ! = n × ( n − 1 ) × ( n − 2 ) . . . × 2 × 1

For a number n, the factorial of n can be written as, n ! = n × ( n − 1 ) !

`color(green)((n+1)! = (n+1) * n! = (n+1) * n * (n-1) * (n-2) * . . . * 3 * 2 * 1`
