274, 301, 426, 769, 1498, 2824, 5026

• each next number is summation of cube of consecutive odd number and Previous one.Odd number is started with 3 e.g.
  274 + 3^3 = 301
  301 + 5^3 = 426
  426 + 7^3 = 769
  769 + 9^3 = 1498
  1498 + 11^3 = 2829
  2829 + 13^3 = 5026
  Therefore wrong term is 2824.

• Tn = T(n-1) + (2n-1)^3 , for n greater than 1, where n is an integer.
  
  T2 = 274 + (2*2-1)^3 = 301
  
  T3 = 301 + (2*3-1)^3 = 426
  
  
  T4 = 426 + (2*4-1)^3 = 769
  
  
  T5 = 769 + (2*5-1)^3 = 2824
  
  
  T6 = 2824 + (2*6-1)^3 = 4155
  
  Hence the sixth term is wrong. That is 5026.
