• If we get the difference of f2nd and 3rd we get 387
  And 5th ,6th is 399
  So from here we are getting the increment of 12 in 387 and399 so its easy to get that the increament will be of 4 in each case like second to third is 387 third to four will get incremented by 391 and four to fifth increment will be 395 and then 399
  So the ans is19261

• start solving from 2nd term.
  the difference of 3rd and 2nd term is 387.
  the difference of 6th and 5th term is 399.
  therefore difference b/n 5th and 4th term must be 393.
  add 393 in 3th term to get 4th term which is 19263.

  3rd-2nd= 18870-18483= 387
  6th-5th= 20055-19656= 393
  393-387= 12 we have to find difference b/n 3no. : 18870, ?, 19656
  so, 12/3 = 4
  now the difference b/n the number increases by "+4"
  387+4= 391(diff b/w 3rd n 4th) ; 391+4= 395 (diff b/n 4th n 5th) ; 395+4 = 393 (diff b/n 5th n 6th)
  18870-18483= 387 ; 18870+391=19261 ; 19656-19261=395 ; 20055-19656= 399
  so ans is : 19261
