A training program requires a pilot to fly circuits of an airfield. Each day, the pilot flies three more circuits than the previous day. On the fifth day, the pilot flew 14 circuits. How many circuits did the pilot fly (a) on the first day? \( [2 \) marks \( ] \) (b) in total by the end of the fifth day? \( [2 \) marks \( ] \) (c) in total from the end of the \( n^{t h} \) day to the end of the ( \( \left.2 n\right)^{\text {th }} \) day? Simplify your answer. [3 marks]
