Determine the recursive and explicit formulas that describe this sequence.
The recursive function that describes this sequence is f(1) = 7, f(n) = f(n - 1) , n ≥ 2.
The explicit function that describes this situation is f(n) = n , and f(10) =

Answer 1

Given:

f(1)=7

f(n)=f(n-1) for n>=2.

Since f(n)=f(n-1), so for all values of n >=2, f(n)=f(n-1)=f(n-2)....f(2)=f(1)=7

So the explicit formula is

f(n)=7

and f(10)=7

Answer 2

Answer:

the function that describes the sequences is f(1)=7, f(n)= f(n--1) (+6), n >2

the explicit function that describes this situation is f(n)= (6) n (+1), and f(10) = 61
