We have coordinates here: (75, 301) and (1,5).
\n" ); document.write( "To find the common difference, we need the slope formula:
\n" ); document.write( " $\"%28Y2+-+Y1%29+%2F+%28X2+-+X1%29\"$
\n" ); document.write( "Putting in our X,Y coordinates, we get
\n" ); document.write( " $\"%28301-5%29%2F%2875-1%29\"$
\n" ); document.write( "which is
\n" ); document.write( "296/74 = 4.
\n" ); document.write( "The common difference is 4. \n" ); document.write( "

\n" );
