Answer:

U1  = -5

Un = Un-1 + 13  when n≥2

Step-by-step explanation:

-5, 8, 21, 34, 47, 60

60-47=13

47-34=13

34-21=13

21-8=13

8-(-5)=13

then the common differences q for this arithmetic sequence Un is 13

Then the recursive formula is:

U1 = -5

Un= Un-1 + r  when n≥2

U1 = -5

Un= Un-1 + 13  when n≥2
