Set up a table of values for k and the argument, (-2k+8).
\n" ); document.write( "EXCEL is a great program to do this.
\n" ); document.write( "k=1, -2k+8=-2(1)+8=6
\n" ); document.write( "k=2, -2k+8=-2(2)+8=4
\n" ); document.write( "k=3, -2k+8=-2(3)+8=2
\n" ); document.write( "k=4, -2k+8=-2(4)+8=0
\n" ); document.write( "k=5, -2k+8=-2(5)+8=-2
\n" ); document.write( "k=6, -2k+8=-2(6)+8=-4
\n" ); document.write( "k=7, -2k+8=-2(7)+8=-6
\n" ); document.write( "k=8, -2k+8=-2(8)+8=-8
\n" ); document.write( "k=9, -2k+8=-2(9)+8=-10
\n" ); document.write( "Sum the first nine terms,
\n" ); document.write( "\"cross%286%2B4%2B2%2B0%2B%28-2%29%2B%28-4%29%2B%28-6%29%29%2B%28-8%29%2B%28-10%29=-18\"
\n" ); document.write( "\"sum%28+%28-2k%2B8%29%2C+1%2C+9+%29=-18\"
