Find the Second Term A_n=n(n-1)(n-2)

$A_{n} = n (n - 1) (n - 2)$

Step 1

Substitute in the value of $n$ to find the $n$ th term.

$A_{2} = (2) ((2) - 1) ((2) - 2)$

Step 2

Subtract $1$ from $2$ .

$A_{2} = 2 \cdot (1 ((2) - 2))$

Step 3

Multiply $2$ by $1$ .

$A_{2} = 2 ((2) - 2)$

Step 4

Subtract $2$ from $2$ .

$A_{2} = 2 \cdot 0$

Step 5

Multiply $2$ by $0$ .

$A_{2} = 0$
