Question

A king wanted to reward his advisor, a wise man of the kingdom. So
he asked the wiseman to name his own reward. The wiseman thanked
the king but said that he would ask only for 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 30 days. Without making calculations, find how
many coins will the advisor get in that month?
