Use the drop-downs to answer the questions about this geometric sequence. –243, 81, –27, 9 … What is the common ratio? What is the fifth term in the sequence? What is the sixth term in the sequence?

a= -243

r=81/-243, r= -0.33(common ratio)

to find the 5th term; T5= -243×(0.33)^(5-1)

T5= -243 × (0.33)^4

T5= -3

to find the 6th term; T6= -243 ×(0.33)^(6-1)

T6= -243 ×(-0.33)^5

T6= 1

Answer above is correct
