A factory makes (150) toys on the first day and (20) more toys each next day. How many toys are made on the (6)th day?

Answer and explanation

Correct answer: 250

The daily production forms an AP with first term \(a=150\) and common difference \(d=20\). Thus, the production on the sixth day is \(a_6=a+(6-1)d=150+5\times20=250\). The answer 270 results from adding 20 six times, but there are only five increases after the first day. Exam tip: use \(a_n=a+(n-1)d\) for the \(n\)th term.
