Find the three missing terms between 5 and 405 in the geometric sequence Please check my answers to see I got the question right

OpenStudy (campbell_st):

then 405 is the 5th term using the term in a gometric sequence \[T _{n} = ar^{n-1}\] \[405 = 5r^{5-1}\] solve for r then you can find the missing terms

OpenStudy (anonymous):

Would the missing terms be 15, 45, and 135?

OpenStudy (anonymous):

I got those answers by multiplying each number by 3

OpenStudy (campbell_st):

looks like it
