The positive integers are written in a triangular array as shown

The row in which the number 2005 will be, is

nth term of the given sequence should be less than or equal to 2005  since the number 2005 can be anywhere in the whole row but atleast at the 1st position.

P is a point inside the triangle ABC. Lines are drawn through P parallel to the sides of the triangle. The areas of the three resulting triangles with a vertex at P are 4, 9 and 49, then the area of ABC is

ratio of sides of similar triangles = square root of the ratio of areas of the triangles. the converse is also true.
