a high school senior is concerned about attending college because she knows that many college students require more than 4 years to complete a bachelors degree. at the 0.10 level of significance, test the claim of her guidance counselor who states that the mean time required to complete a bachelors degree is greater than 5 years. sample data from 500 randomly selected college graduates consists of a mean of 5.15 years with a standard deviation of 1.68 years

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
