[JMO 2001 B2 Edited] In a sequence, each term after the first is the sum of the squares of the digits of the previous term. Thus if the first term were 12, the second term would be 1 2 + 2 2 = 5, the third term 5 2 = 25, the fourth term 2 2 + 5 2 = 29, and so on. Find the 2001 st term of the sequence whose first term is 25.
