Question

A sequence is defined by the recursive function in + 1) =An). If $(3) = 9, what is (1) ?​

Answer 1

For the recursive function, f(n+1) = one-half(n)

Thus, when n = 2,

f(3) = 9

If n = 1,

f(2) = 9×3

f(2) = 27

If n = 0,

f(1) = 27 ×3

f(1) = 81

Answer 2

He answer to your question is 81
