Series appears to be like 2+12+22+32+... ADDED TO 7+17+27+37+...
\n" ); document.write( "OR
\n" ); document.write( "The series for \"2%2B10%28n-1%29\" ADDED TO the series for \"7%2B10%28n-1%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If you want the series for the first 10 terms, then
\n" ); document.write( "using the arithmetic sum formula\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( ".
\n" ); document.write( "....\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Do the sum of both of these for their FIRST FIVE TERMS.
\n" ); document.write( "Use sum of arithmetic series formula.
