Anewborn infant usually triples its birth weight by age one year. baby carter weighed 28 pounds on his first birthday. if this were triple his birth weight (b), which equation below could be used to determine his birth weight? (1) b/3=28. (2) b-3=28. (3) 2b=28. (4) b+3=28. (5) 3(b+3)=28

see explanation

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
