Standard +0.3 This is a straightforward application of standard AP and GP formulas with clear given information. Students must find common difference and ratio from given terms, then calculate the tenth terms and subtract. While it requires multiple steps, each is routine and the question structure is typical for C2 level, making it slightly easier than average.
An arithmetic progression (AP) and a geometric progression (GP) have the same first and fourth terms as each other. The first term of both is 1.5 and the fourth term of both is 12. Calculate the difference between the tenth terms of the AP and the GP. [5]
