Question 1169262
You know because it is given, term at index 3 is 8, term at index 8 is 1/4; and you know  because it is given that sequence is a GEOMETRIC sequence.  You then also KNOW that common ratio between each term.  FIND THAT COMMON RATIO, r.


Index 3,  8.
From index 3 to index 8,  {{{8*r*r*r*r*r=highlight_green(8r^5=1/4)}}};


{{{r^5=(1/4)/8}}}

{{{r^5=1/32}}}

{{{r^5=(1/2)^5}}}

{{{highlight_green(r=1/2)}}}
