<s>[INST] The focus of a lens is \( 0.2 \) meters from the center of the lens. A real image is formed at a distance \( d \) behind the lens on a screen when an object is placed at a distance \( 0.5 \) meters in front of the lens. 
What is the distance \( d \) that will take to be at the image or that is the image distance where the object distance is \( 0.5 \) meters and the focal length of the lens is \( 0.2 \) meters?[/INST]
