In an arithmetic sequence, the difference between consecutive terms is constant. This difference is called the common difference ($d$).

Step 1: Find the Common Difference

$d = 3 - (-2) = 5$ $d = 8 - 3 = 5$ $d = 13 - 8 = 5$ $d = 18 - 13 = 5$ Since the common difference is 5, the sequence follows the pattern of adding 5 to each term.

Step 2: Find the Next Term

$\text{Next term} = 18 + 5 = 23$

Answer:

$\mathbf{23}$

Tip:

To find any term in an arithmetic sequence, use the formula:
$a_n = a_1 + (n-1) d$
where $a_1$ is the first term, $d$ is the common difference, and $n$ is the term number.
