\n" ); document.write( "\n" ); document.write( "        In this my post I want to explain you  WHY  your problem formulation is  INCORRECT.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "When you say  \" Find the sum to Infinity of the following Sequence : 18, 12, 8, . . .\",\r
\n" ); document.write( "\n" ); document.write( "the sequence is,  actually,  UNDEFINED :  we don't know how to continue it.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We only can hypothesize,  what the sequence,  actually,  is,  but making such hypotheses is not the way to solve  Math problems. \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In Math textbooks, such formulations are  NEVER  USED  and are not allowable: \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "        NO  ONE  professional  Math writer will write this way.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The correct formulation is  \" Find the sum to infinity of the following  geometric  sequence:  18, 12, 8, . . .\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then the sequence is defined by a  UNIQUE way,  and the problem is good for the solution.\r

\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Which means very low level of mathematical education,  not sufficient for writing  Math problems.\r
