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

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
