c(1)=−3
; c(r)=c(r+1)−4

c of 1 is equal to negative 3 ; c of r is equal to c of open paren r plus 1 close paren minus 4

c(1)=−3
; c(r)=c(r−1)+4

c of 1 is equal to negative 3 ; c of r is equal to c of open paren r minus 1 close paren plus 4

c(1)=−3
; c(r)=cr−1+4

c of 1 is equal to negative 3 ; c of r is equal to c sub r minus 1 baseline plus 4

c(1)=−3
; c(r)=c(r+4)−1

Answer 1

The correct option is:

c(1) = −3 ; c(r) = c(r−1) + 4

(That is option 3 — replace the subscript r with function notation c(r).)
