A factory makes (200) toys on the first day and (25) more toys each next day. How many toys are made on the (5)th day?

Answer and explanation

Correct answer: 300

The daily production forms an AP with first term 200 and common difference 25. The production on the fifth day is \(a_5=a+(5-1)d=200+4\times25=300\). Adding 25 five times gives 325, but only four increases occur after the first day. Exam tip: use \(a_n=a+(n-1)d\) for the \(n\)th term of an AP.
