+#The sequence of triangle numbers is generated by adding the natural numbers.
+#So the 7th triangle number would be 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28. The first
+#ten terms would be:
+#
+#1, 3, 6, 10, 15, 21, 28, 36, 45, 55, ...
+#
+#Let us list the factors of the first seven triangle numbers:

+#15: 1,3,5,15
+#21: 1,3,7,21

+Longest Collatz sequence

+The following iterative sequence is defined for the set of positive integers:

+n → n/2 (n is even)
+n → 3n + 1 (n is odd)
+
+Using the rule above and starting with 13, we generate the following sequence:

+13 → 40 → 20 → 10 → 5 → 16 → 8 → 4 → 2 → 1
+It can be seen that this sequence (starting at 13 and finishing at 1) contains 10 terms. Although it has not been proved yet (Collatz Problem), it is thought that all starting numbers finish at 1.
+
+Which starting number, under one million, produces the longest chain?
