Let $\"s+=+k%2At%5E2\"$ .
\n" ); document.write( "When t = 5, s = 150.
\n" ); document.write( "So $\"150+=+k%2A5%5E2\"$
\n" ); document.write( "or $\"150+=+k%2A25\"$
\n" ); document.write( "or k = 6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So $\"s+=+6%2At%5E2\"$
\n" ); document.write( "When t = 4, $\"s+=+6%2A4%5E2+=+6%2A16\"$ = 96 \n" ); document.write( "

\n" );
