Which recursive formula can be used generate the sequence shown where f (1) = 5 and n>1?

5,-1,-7,-13,-19, ...

A) f (n+1) = (n) + 6

B) f (n) = f (n+1) - 6

C) f (n+1) = f (n) - 6

D) f (n+1) = - 6f (n)

So we notice that the difference between the nubmers is 6 (5-6=-1, - 1-6=-7, etc)

so therefor it must be something with - 6, and n>1 so

f (n) = - 6n

the difference to the next erm is 6 so the answe ris C

f (n+1) = f (n) - 6

C
