find the nth term of each arithmetic sequence then graph the first five terms of the sequence \r
\n" ); document.write( "\n" ); document.write( "9,13,17,21
\n" ); document.write( ".
\n" ); document.write( "Notice that for your series, there is a \"constant\" difference of 4 between the numbers. If so, you can apply the following \"arithmetic sequence\" formula:
\n" ); document.write( ".
\n" ); document.write( "Ref:http://www.mathwords.com/a/arithmetic_sequence.htm
\n" ); document.write( ".
\n" ); document.write( "You can use the following formula to find the nth term:
\n" ); document.write( "an = a1 + (n – 1)d
\n" ); document.write( "where
\n" ); document.write( "an = the nth term
\n" ); document.write( "a1 = first value of the series
\n" ); document.write( "n = desired sequence number
\n" ); document.write( "d = the constant difference (4)
\n" ); document.write( ".
\n" ); document.write( "They gave you the first four terms so the 5th term is simply 4 more than the 4th term.
\n" ); document.write( ".
\n" ); document.write( "The entire sequence:
\n" ); document.write( "9,13,17,21,25
\n" ); document.write( " \n" ); document.write( "
\n" );
