(geometric sequences) 15 points 1) find the next three terms for the geometric sequence: 84035, 12005, 1715, 245, enter your answers as numbers separated by commas, like this: 42, 52, 62 if necessary, use the / symbol to indicate fractions, like this: 42, 52, 62/3 2) the third term of a geometric sequence is 4. the sixth term is -108. what is the first term? enter your answer as a number, like this: 42 or as a fraction, like this: 42/15 3) in the geometric sequence shown, the common ratio is 4. find the missing values. a5, 24, a7, a) a7 = 6 b) a5 = 96 c) a7 = 96 d) a5 = 6 4) look at the following sequence: 5, 20, 80, 320, determine whether the sequence is geometric. if it is geometric, find its common ratio. enter your answer in one of two forms: if your answer is yes, it is geometric and you found the value of r, enter it like this: yes, 42 if your answer is no, it is not geometric, enter it like this: no
