Answer 2

Answer:

21, 23

Step-by-step explanation:

This is an arithmetic sequence since there is a common difference between each term. In this case, adding 2 to the previous term in the sequence gives the next term. In other words, $a_{n}$ = $a_{1}$ + d (n−1)

Arithmetic Sequence: d = 2

$a_{n}$ = $a_{1}$ + d (n−1). This is the formula of an arithmetic sequence.
