Question

Given the recursively defined formula c1 =- 3, c, = Cr-1+4, determine which option is the correct function notation. (1 point)

1 c(1) =- 3;c(r) = Cr-1+4
2 c(1) =- 3;c (r) = c (r-1) +4
3 c(1) =- 3;c(r) =c(r+4) -1
4 c(1) =- 3;c(r)=c(r+1)-4

Answer 1

Answer: 2.

Correct function notation is c(1) = -3 and c(r) = c(r-1) + 4, since the recursive step uses the previous term plus 4.
