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]
