A particle P starts from the point z0 = 1 + 2i, where i = -1. It moves first horizontally away from origin by 5 units and then vertically away from origin by 3 units to reach a point z1. From z1 the particle moves 2 units in the direction of the vector i + j and then it moves through an angle 2i in anticlockwise direction on a circle with centre at origin, to reach a point z2. The point z2 is given by
