I WILL GIVE BRAINLIEST PLEASE HELP T-T !! A sequence is defined by the recusive function fin + 1) = fn). Iff3) = 9, what is f(1) ?
- 1
- 3
- 27
- 81

9 is the answer

Step-by-step explanation:

“ Since f(n+1) = f(n)

If n= 1

f(2) = f(1)

if n= 2

f(3) = f(2) = 9 {since f(3) is 9}

Since f(2) is now 9 and f(2) = f(1), therefore f(1) will also be 9.

No answer!”
