The 4800th term of the sequence 1, 3, 3, 3, 5, 5, 5, 5, 5, 7, 7, 7, 7, 7, 7, 7, 9, ………… will be

139 is the term. The Sum of n odd numbers is n square. That means the sum till the 70th bracket is going to be 4900. The terms in the 70th bracket are going to be 2n-1 aka 2(70) -1 = 139. 139 terms written 139 times which means quite obviously 4800th term is also going to be 139. Hence 139 is the answer

70 th

139 is the answer
here the term is 70th odd num so its 2n-1 where n is 70

70 is the answer.
