Before looking for papers, it is crucial to confirm which level you need. In HKIMO, the Senior Secondary group typically corresponds to:

The HKIMO is divided into two primary stages: the Heat Round (preliminary) and the Final Round. hkimo+past+papers+senior+secondary

Set (n^2 + 5n + 6 = k^2). Complete the partial square: ((n + 2.5)^2 = n^2 + 5n + 6.25). Thus (n^2 + 5n + 6 = k^2 \implies (2n+5)^2 - 4k^2 = 1 \implies (2n+5 - 2k)(2n+5 + 2k) = 1). Since integer factors of 1 are only (1 \times 1) or ((-1)\times(-1)), solving gives (n = -2, -3). Check: ((-2)^2 + 5(-2) + 6 = 0 = 0^2), ((-3)^2 + 5(-3) + 6 = 0). Answer: (n = -3) or (n = -2). Before looking for papers, it is crucial to

When you find a paper, understand that HKIMO contests usually follow a distinct format (though this varies slightly year by year):
