A craftsperson makes (9) toys on the first day and (3) more toys each next day. How many toys are made on the (8)th day?

Answer and explanation

Correct answer: 30

The number of toys made each day forms an AP with first term \(a=9\) and common difference \(d=3\). The eighth term is \(a_8=a+(8-1)d=9+7\times3=30\). Therefore, the correct answer is 30. Choosing 27 would add the increase only 6 times, whereas there are 7 increases from day 1 to day 8. Exam tip: use \(a_n=a+(n-1)d\), taking care to use \(n-1\), not \(n\).
