1) first term value is 9 and note that the differences for the given values is 6
\n" ); document.write( "this leads to an arithmetic progression where
\n" ); document.write( "the common difference between successive terms is 3 and we start with 9, therefore
\n" ); document.write( "a(n) = 9 + (n-1)*3 where * means multiply and n is the nth term
\n" ); document.write( "2) first term is 12 and note that successive differences for given values is 2
\n" ); document.write( "the common difference is 2 and first term value is 12, therefore
\n" ); document.write( "a(n) = 12 + (n-1)*2\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
