TopicArithmetic Sequences and Series
TypeFind term or common difference
DifficultyModerate -0.3 This is a straightforward arithmetic progression problem requiring standard formulas (nth term and sum). Students must set up two simultaneous equations from given information and solve for the first term and common difference, then find the 4th term. While it requires multiple steps, the techniques are routine and commonly practiced, making it slightly easier than average.
