Answer:

[tex]a_{7}=\frac{256}{729}[/tex]   or   [tex]a_{7}=0.35[/tex]

Step-by-step explanation:

[tex]a_{n} =a_{1}* r^{n-1}[/tex]

[tex]a_{7}=4*\frac{2}{3}^{7-1}[/tex]

[tex]a_{7}=4*\frac{2}{3}^{6}[/tex]

[tex]a_{7}=4*\frac{64}{729}[/tex]

[tex]a_{7}=\frac{256}{729}[/tex]

or

[tex]a_{7}=0.35[/tex]
