In this question, one term in the number series is wrong. Find out the wrong term



93, 309, 434, 498, 521, 533



A. 309
B. 434
C. 498
D. 521

• d
  the difference between 309-93=216
  the difference between 434-309=125
  and so on... the difference series would be 216,125,64,23,12
  and 216=6*6*6
  125=5*5*5*
  64=4*4*4
  but 23 doesnot fit acording to this sequence so the answer would be 521

• Answer is D.
  93 + 6^3 = 309
  309 + 5^3 = 434
  434 + 4^3 = 498
  498 + 3^3 = 525 (not 521)
  525 + 2^3 = 533

• 309-93=216=6^3
  434-309=125=5^3
  498-434=64=4^3
  521-498=27=3^3
  533-521=12 ( 12 is not a perfect cube )
  Therefore the 521 is wrong.
  It must be 498 + 3^3 = 498 + 27 = 525
  
  Therefore the answer is D. 521
