Question 967501
If this is a geometric sequence X , 3 ,17 what is the value of X?
<pre>

In a geometric sequence, {{{

matrix(1,2,2nd,term)/matrix(1,2,1st,term)}}}{{{""=""}}}{{{

matrix(1,2,3rd,term)/matrix(1,2,2nd,term)}}}{{{""=""}}}{{{matrix(1,2,common,ratio)}}}

{{{3/X}}}{{{""=""}}}{{{17/3}}}{{{""=""}}}{{{matrix(1,2,common,ratio)}}}

Cross-multiply:

{{{17X}}}{{{""=""}}}{{{9}}}

{{{X}}}{{{""=""}}}{{{9/17}}}
