Let x,y,z be first 3 term of AP.since x,y,z are in AP\r
\n" ); document.write( "\n" ); document.write( "y=(x+z)/2 => 2y = x+z-------(1)
\n" ); document.write( "Given that,
\n" ); document.write( " x+y+z=15-----------(2)
\n" ); document.write( "xyz=45-------(3)
\n" ); document.write( "Now substituting (1) in (2)
\n" ); document.write( "3y=15=>y=15/3=5
\n" ); document.write( "y=5
\n" ); document.write( "substituting y=5 in (2)
\n" ); document.write( "x+z=10=>x=10-z-----(4)Now again substituting y=5 &(4) in (3)
\n" ); document.write( "(10-z)5(z)=45
\n" ); document.write( "5z^2-50z+45=0
\n" ); document.write( "z^2-10z+9=0
\n" ); document.write( "After solving,we get two values for z=1,9
\n" ); document.write( "when z=1,then x=9
\n" ); document.write( "when z=9,then x=1
\n" ); document.write( " \n" ); document.write( "
\n" );
