1 + (2 + 2) = 5
2 + (3 + 3) = 8
3 + (4 + 4) = 11
4 + (5 + 5) = 14
--------------------
5 + (8 + 8) = 5 + 16 = 21
8 + (11 + 11) = 8 + 22 = 30
11 + (14 + 14) = 11 + 28 = 39 (primul numar aflat)
-----------------
21 + (30 + 30) = 21 + 60 = 81
30 + (39 + 39) = 30 + 78 = 108 (al doilea numar aflat)
81 + (108 + 108) = 81 + 216 = 297 (al treilea numar aflat)
