The next two numbers of the geometric sequence will be 27 , 81.
Geometric Sequence or Geometric Progression is defined as a sequence where every term is multiplied by a constant fixed number to get the next term except the first term.
For Example ; 2,6,18,54,..... This is a Geometric sequence as every next term except the first term is multiplied with 3.
Geometric Sequence is denoted by 
Its general term is denoted by
, where a is the first term
r is the common ratio
n is the number of term in the sequence.
According to the given question
given the first two term = 3,9
So a=3 …..(1)
next we need common ratio "r" for this we divide second term by first term .
that is
.
r=9/3
r=3.
The next term of the sequence will be third and fourth term i.e.
.
( using general formula for GP)
Substituting the value as a=3 and r=3

Now

Substituting the value as a=3 and r=3


Therefore , The next two numbers of the geometric sequence will be 27 , 81.
