LET X BE THE FIRST NUMBER.
\n" ); document.write( "4X IS THE NEXT NUMBER.
\n" ); document.write( "X=100 IS THE NEXT NUMBER.
\n" ); document.write( "X+4X+X+100=286
\n" ); document.write( "6X=286-100
\n" ); document.write( "6X=186
\n" ); document.write( "X=186/6
\n" ); document.write( "X=31 ANS. FOR THE FIRST NUMBER.
\n" ); document.write( "4*31=124 ANS. FOR THE NEXT NUMBER.
\n" ); document.write( "31+100=131 ANS. FOR THE NEXT NUMBER.
\n" ); document.write( "PROOF:
\n" ); document.write( "31+124+131=286
\n" ); document.write( "286=286
\n" ); document.write( "
\n" );
