Five houses stand in a row numbered 1 to 5. House 1 is Red and House 5 is White. The Blue house is somewhere between Red and Green. The Yellow house is directly between Blue and Green. What color is House 2?
Blue
Houses 2, 3, 4 must be Blue, Yellow, and Green. Since Yellow is directly between Blue and Green, the order must be Blue-Yellow-Green or Green-Yellow-Blue. Since Blue is between Red (1) and Green, Blue must be closer to Red. Thus House 2 is Blue, House 3 is Yellow, and House 4 is Green.
