Answer is

Ni² ⁺ (aq) + 6NH₃ (aq) ⇌ [Ni (NH₃) ₆]²⁺

When the concentration of Ni²⁺ (aq) increases, according to the Le Chatelier’s principle system tries to become equilibrium by reducing the increased factor. To do that, the concentration of Ni²⁺ (aq) should be reduced. Hence, the forward reacted should be promoted to reduce the Ni²⁺ (aq) concentration.
