Complete the recursive formula of the arithmetic sequence-3,-1,1,3,
b(1)=
b(n) = b(n-1)+

b(1) = -3

b(n) = b(n-1) + 2

Step-by-step explanation:

Notice that there is a common difference in the sequence : each term is the previous one PLUS 2. Then the common difference "d" is 2 making this sequence an arithmetic sequence

b(1) = -3

b(n) = b(n-1) + 2
