What is the rule for this pattern 9 13 17 21 25?

The rule for the pattern 9, 13, 17, 21, 25 is that each number increases by 4 from the previous number. This can be expressed mathematically as: each term can be represented by the formula ( a_n = 9 + 4(n - 1) ), where ( n ) is the position of the term in the sequence. Thus, the pattern continues by adding 4 to the last number to generate the next one.
