The series consists of squares and cubes of consecutive natural numbers i.e., 12 , 13, 22 , 23 , 32 , 33 , 42 ................. So, missing term = 43 = 64
Each term in the series is obtained by subtracting from the preceding term the number formed by the first three digits of the preceding term, So, missing term = 5242 - 524 = 4718
The pattern followed is: n the term + (n + 1)th term + (n + 1) = (n + 2)th term Thus, 1st term + 2nd term + 2 = 3rd term; 2nd term + 3rd term + 3 = 4th term and so on. So, missing term = 6th term = 4th term + 5th term + 5 = 24 + 41 + 5 = 70
