The general formula of an Arithmetic sequence is:
[tex] a_{n}= a_{1}+(n-1)*d [/tex]
Comparing this formula with the given formula, we can write:
Common Difference = d = 5
Since, every term of an Arithmetic sequence can be obtained by adding the common difference to the previous term, so we can write the recursive formula as:
[tex] a_{n} = a_{n-1} +d[/tex]
For the given sequence we can write:
[tex] x_{n} = x_{n-1} +5[/tex]
So, the answer to this question is 5
