Which of the following is a correct recursive definition for the arithmetic sequence k that starts 12, 6, ...?
k(1) = 12,
k(n) = k(n-1) + 6 for n > 2
k(1) = 12,
k(n) = k(n-1) * 2 for n > 2
* is multiplication
k(1) = 12,
k(n) = k(n-1) * 1/2 for n > 2
* is multiplication
k(1) = 12,
k(n) = k(n-1) - 6 for n > 2
