Question 948351

the common ratio of { {{{2}}}, {{{4}}},{{{ 8}}}, {{{16}}} }?

first term is {{{2}}}, if you multiply it by {{{2}}} you will get second term {{{4}}}
{{{2*2=4}}}, continue multiplying by {{{2}}}
{{{4*2=8}}}, 
{{{8*2=16}}}....as you can see, the common ratio is {{{2}}} 

then next three terms will be

{{{16*2=32}}} 

{{{32*2=64}}}

{{{64*2=128}}} 

{ {{{2}}}, {{{4}}},{{{ 8}}}, {{{16}}},{{{32}}},{{{64}}},{{{128}}}   }
