Problem: in a certain quiz that consists of 10 questions , each question after the first is worth 4 points more than the preceding question . if the 10 questions on the quiz are worth a total of 300 points , how many points is the third question worth ?
Rationale: "x x + 4 x + 8 x + 12 x + 16 x + 20 x + 24 x + 28 x + 32 x + 36 10 x + 180 = 300 10 x = 120 x = 12 3 rd question = x + 8 = 12 + 8 = 20 answer d"
annotated_formula: add(divide(300, 10), subtract(subtract(10, 4), const_1))
