You can put this solution on YOUR website!
Now this one is different just because its got decimals,but that doesnt mean that its difficult!
\n" ); document.write( " The problem is 2.1,4.2,8.4,17.6,....
\n" ); document.write( "4.2-2.1=2.1
\n" ); document.write( " Now 2.1 to 4.2 is 2.1 (add)
\n" ); document.write( "If each decimal is going up or increasing by 2.1 the yes it is arthemetic. Lets see- 4.2+ 2.1=6.3 NO
\n" ); document.write( " 8.4 +2.1=9.5 NO
\n" ); document.write( "No this problem has no common difference. \n" ); document.write( "
\n" );
