Answer:
Answer is [tex]3^{4-n}[/tex]
Step-by-step explanation:
It is 29 in place of 27 . and Its a geometric series with first term 27 and common ratio [tex]\frac{1}{3}[/tex]
and general formula for given sequence is given by [tex]a (r)^{n-1}[/tex]
so plugging the value of a and r ,we get
[tex]27 ([tex]\frac{1}{3}[/tex])^{n-1}[/tex]
[tex]3^3(\frac{1}{3} )}^{n-1}[/tex]
[tex]3^{4-n}[/tex]
