# (a) a = , r = 3/ = (b) a = , r = (a) a = , r = 3/ = Let 729 be the nth term of the G.P.

an = arn-1

729 = ( )n-1

( )12 = ( )n

n = 12

Therefore 729 is the 12th term of the G.P.

(b) a = , r = Let be the nth term of the G.P.

an = arn-1 =   = n = 9

Therefore 1/19683 is the 9th term of the G.P.
