An arithmetic sequence is represented by the explicit formula A(n) = 2 − 5(n − 1). What is the recursive formula?
A.
A(n) = A(n − 1) + 5
B.
A(n) = A(n − 1) + 2
C.
A(n) = A(n − 1) − 5
D.
A(n) = A(n − 1) − 2
An = 2 - 5 (n - 1) generates the sequence 2 , -3, - 8, -13 ....... we are subtracting 5 form the previous term to get the successive term
So..... An = A(n - 1) - 5 answer "C"
