$0$ , $4$ , $8$ , $12$ , $16$

Step 1

This is an arithmetic sequence since there is a common difference between each term. In this case, adding $4$ to the previous term in the sequence gives the next term. In other words, $a_{n} = a_{1} + d (n - 1)$ .

Arithmetic Sequence: $d = 4$

Step 2

This is the formula of an arithmetic sequence.

$a_{n} = a_{1} + d (n - 1)$

Step 3

Substitute in the values of $a_{1} = 0$ and $d = 4$ .

$a_{n} = 0 + 4 (n - 1)$

Step 4

Add $0$ and $4 (n - 1)$ .

$a_{n} = 4 (n - 1)$

Step 5

Apply the distributive property.

$a_{n} = 4 n + 4 \cdot - 1$

Step 6

Multiply $4$ by $- 1$ .

$a_{n} = 4 n - 4$
