Question

the following is a geometric sequence 3,4,7,9...
true or false

Answer 1

the following sequence is a geometric sequence if the common ratio,r is equal\[T_1=3\]\[T_2=4\]\[T_3=7\]\[T_4=9\]\[common~ratio,r=\frac{ T_2 }{ T_1 }\]\[r=\frac{ 4 }{ 3 }\]\[r=\frac{ T_3 }{ T_2 }\]\[r=\frac{ 7 }{ 4 }\]\[r=\frac{ T_4 }{ T_3 }\]\[r=\frac{ 9 }{ 7 }\]

Answer 2

we can see that\[\frac{ T_2 }{ T_1 }\color{red}{\neq} \frac{ T_3 }{ T_2 }\color{red}{\neq} \frac{ T_4 }{ T_3 }\]

Answer 3

If the common ratio are not equal,therefore,it is not a geometric sequence

Answer 4

so false

Answer 5

yes!
