Question

can some one help me ​

Answer 1

Answer:

geometric sequences are given below

1,3,9,27,81

5,10,20,40,80,160

10,5,205,1.25,0.625,0.3125

Step-by-step explanation:

geometric sequences are those sequences whose common ratio are same

so that $\frac{3}{1}=\frac{9}{3}=\frac{27}{9}=\frac{81}{27}$

           $\frac{10}{5}=\frac{20}{10}=\frac{40}{20}=\frac{80}{40}=\frac{160}{80}$

$\frac{5}{10}=\frac{2.5}{5}=\frac{1.25}{2.5}=\frac{0.625}{1.25}=\frac{0.3125}{0.625}$

1,3,9,27,81

5,10,20,40,80,160

10,5,2.5,1.25,0.625,0.3125

these are in geometric sequences
