A nursery sells (9) pots on the first day and (3) more pots each next day. How many pots are sold in (12) days?

Answer and explanation

Correct answer: 306

The number of pots sold each day forms an arithmetic progression with first term \(a=9\), common difference \(d=3\), and number of terms \(n=12\). Thus, \(S_{12}=\frac{12}{2}[2(9)+(12-1)3]=6(51)=306\). Therefore, 306 pots are sold in 12 days. Option 294 results from not accounting correctly for the daily increase or the number of terms. Exam tip: In AP word problems, first identify \(a\), \(d\), and \(n\), then apply the formula for \(S_n\).
