The explicit rule for a sequence is an=14-9n what is the recursive rule for the sequence?

The explicit rule for the sequence is

Let us put n=1, we get

Now let n=2,

Let n=3,

Similarly, in this manner we obtain a sequence as

5, -4, -13, -22,.....

Since we can clearly observe that the first term is '5' and common difference is '-9'.

So, we get recursive rule for the sequence as:

, where .
