You can put this solution on YOUR website!
Here,
\n" ); document.write( "1st term(a)=2
\n" ); document.write( "common ratio(r)=t2/t1=3
\n" ); document.write( "So,We have,
\n" ); document.write( "Sn=a(r^(n-1))/(r-1)
\n" ); document.write( "S12={2(3^(12-1)}/(3-1)
\n" ); document.write( "By solving this we can get sum of 12 terms=3^11
\n" ); document.write( "
\n" );
