Concept:In each given set, the three numbers form an arithmetic progression with a common difference of 75.Explanation:Check the first set (153,228,303):228−153=75303−228=75So the difference between consecutive numbers is 75.Check the second set (129,204,279):204−129=75279−204=75The same difference of 75 is followed.Now test each option:Option 1: (168,247,342)247−168=79, which is not 75.Option 2: (191,266,381)266−191=75381−266=115î€ =75.Option 3: (172,237,322)237−172=65î€ =75.Option 4: (113,188,263)188−113=75263−188=75Hence, option 4 satisfies the required relation.Answer:Option 4: (113,188,263)
