In the table below the first difference increases by 2 each time.<br />
We can, therefore, predict that if there are seven clubs there will be 12 more visits than when<br />
there were six clubs. We can also complete the following table.<br />
No. <strong>of</strong><br />
clubs<br />
No. <strong>of</strong><br />
visits<br />
4 5 6 7 8 9 10 12 14 20 30 50<br />
12 20 30 42<br />
Using this technique we can count up to 50 clubs to determine the number <strong>of</strong> visits made. Obviously,<br />
this would be a time-consuming process. It would, therefore, be better, if we could determine<br />
a relationship between the number <strong>of</strong> clubs <strong>and</strong> the number <strong>of</strong> visits – in this way we would<br />
be able to predict the number <strong>of</strong> visits as long as we knew the number <strong>of</strong> clubs.<br />
This relationship is a vertical one (top-down) <strong>and</strong> is shown below:<br />
