color(blue)(d=3

#### Explanation:

The arithmetic sequence provided is :
$2 , 5 , 8 , 11$

There is a common difference maintained between any two consecutive numbers of an arithmetic sequence.

$d = 5 - 2 = 3$
$d = 8 - 5 = 3$
$d = 11 - 8 = 3$

So the common difference of this arithmetic progression is
color(blue)(d=3
