Concept:Identify the pattern of the series, which is n3+1 for n=2,3,4,5,6,7.Explanation:• The given terms are 9,29,65,126,217,344.• Check cubes: 23=8, so 8+1=9 (correct); 33=27, so 27+1=28, but the series has 29 (incorrect); 43=64, 64+1=65 (correct); 53=125, 125+1=126 (correct); 63=216, 216+1=217 (correct); 73=343, 343+1=344 (correct).• The second term should be 28 but is given as 29. Hence 29 is the wrong term.Answer:The wrong term is 29.
