Problem
A farmer uses fertiliser in this manner: 160 kg in the first season, 150 kg in the second season, 140 kg in the third season and so on, reducing the amount by 10 kg each season until he reaches 100 kg in a season.
(i) For how many seasons does this pattern continue?
(ii) Is the sequence of fertiliser amounts a finite AP or an infinite AP?
