patterns  {{{2}}},{{{6}}},{{{4}}},{{{12}}},{{{10}}},{{{30}}},{{{28}}},__,__,__


Every other number is {{{3}}} times the number before it. 
The other numbers are {{{2}}} less than the number before it. 

so, first one is {{{highlight(2)}}}
to get second one multiply first one by {{{3}}}=> {{{2*3=highlight(6)}}}

to get third one subtract {{{2}}} from  second one => {{{6-2=highlight(4)}}}

:

:
{{{28}}} next one will be {{{3*28=highlight(84)}}}
next one will be {{{84-2=highlight(82)}}}

next one will be {{{3*82=highlight(246)}}}
