Complete the recursive formula of the arithmetic sequence 20,26,32,38

A recursive formula for a sequence expresses the -th term as a function of the previous one(s).

In this case, you can see that every term is 6 more than the previous one.

So, the recursive formula is "the -th term is 6 more than the -th term".

In formula, it's written

Since the recursion could go back indefinitely, we usually set a starting point, so that the sequence is fully determined:
