If ticket prices are (40,45,50,55,\ldots), what is the common difference of the prices?
Answer and explanation
Correct answer: 5
The common difference is the difference between two consecutive terms. Here, \(45-40=5\), \(50-45=5\), and \(55-50=5\). Therefore, the common difference of the ticket prices is 5. Option 10 is incorrect because it is not the difference between consecutive terms. Exam tip: To find the common difference in an AP, subtract the first term from the second term.
