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 12 + 22 = 5, the
third term 52 = 25, the fourth term 22 + 52 = 29, and
so on.
Find the first five terms of the sequence whose first
term is 25.
