Q. The 4800th term of the sequence : 1,3,3,3,5,5,5,5,5,7,7,7,7,7,7,7,9……??

[Wonder Boy]

chk the no. of terms of each number

1 is 1 time ,

3 is 3 times ,

5 is 5 times ..

so start calculating the no. of terms somewhere less than 4800

you will get it by adding 1+3+5 +….. +2n-1 <= 4800

1+3+5+…+2n-1 is sum of odd numbers and is equal to n².

so n² <= 4800.

n = 69 since 69² = 4761

Hence next term i.e. 4762th term to 4900th term is  is 70th odd number i.e 70×2-1 = 139 Ans
