A farmer sells (25) kg grain in the first week and (5) kg more each next week. How much grain will he sell in (10) weeks?

Answer and explanation

Correct answer: kg

The weekly sales form an arithmetic progression with first term \(a=25\), common difference \(d=5\), and \(n=10\) terms. Thus, \(S_{10}=\frac{10}{2}[2(25)+(10-1)5]=5(95)=475\) kg. Therefore, option B is correct. Taking 500 kg does not account for the weekly increase correctly. Exam tip: In AP word problems, first identify \(a\), \(d\), and \(n\).
