Answer:

C(1)=13

c(n)=c(n-1)+-7

Step-by-step explanation:

To find what C(1) equals look at the first number in the sequence in this case the sequence starts at 13 that's what C(1) equals

13,6,-1,-8  

To find what c(n) equals you check what the common difference is in this case they are adding -7 or subtracting 7 each time.

13-7=6  

6-7= -1

-1-7=-8            

Then you plug the common difference into the last part it, C(n)=c(n-1)+-7
