Question

A king wanted to reward his advisor, a wise man of the kingdom. So he
asked the wise man to name his own reward. The wise man thanked the
king, but said that he would ask only some gold coins each day for a
month. The coins were to be counted out in a pattern of one coin for the
first day, 3 coins for the second day, 5 coins for the third day and so on for
