Sarah is collecting recyclables for a science project. On the first day she collects 35 recyclable objects. On the second day she has a total of 52 recyclables. On the third day she has a total of 69 recyclables. Determine if the scenario describes an arithmetic or a geometric sequence. Then, write the recursive formula for the sequence described.
On the first day she collects 35 recyclable objects.
On the second day she has a total of 52 recyclables.
On the third day she has a total of 69 recyclables.
52-35 =17
69-52= 17
The difference between two consecutive days collection is 17
Hence it is an Arithmetic sequence

Each day she collects 17 more than the previous day.
The first day she collects 35. So the recursion formula is:
