9 36 144 or -9 36 -144

OpenStudy (anonymous):

how did u get the ans??

OpenStudy (mia99):

Use the nth term formula to find the value of r. In the sequence 2.25, __?__, __?__ ,__?__, 576, a1 is 2.25 and a5 is 576. There are two possible common ratios, so there are two possible sets of geometric means. Use each value of r to find three geometric means.

OpenStudy (anonymous):

can r be two values?

OpenStudy (mia99):

yes

OpenStudy (anonymous):

OpenStudy (mia99):
