Paul is one of the best young chess players in the world.  At only 17 years old, he is already the 8^th highest rated chess player in the world and recently surpassed the former world chess champion in the USA.  When he first began playing chess, Paul's rating could be modeled using a geometric sequence, where the first term represents his rating during month 1 (December 2013).

During month 9 (August 2014), he had a rating of 1475 and during month 15 (February 2015), a rating of 1700.

According to this model, what was Paul’s rating during month 25 (December 2015)?  Round your answer to the nearest whole number.
