Concept:The series alternates between subtracting 20 and adding 25.Explanation:Start with 225.Subtract 20: 225−20=205.Add 25: 205+25=230.Subtract 20: 230−20=210.Add 25: 210+25=235, not 240.Subtract 20: 235−20=215.So the correct series is 225,205,230,210,235,215.The term 240 does not fit the pattern.Answer:240 is the wrong term.
