• 1 3 4 1 4 4
  4 5 5 (+) 4 5(+) 5(+)
  5 8 9 5 9 9
  3 4 5 (-) 3 5(-) 5(-)
  2 4 4 2 4 4
  1 5 4(+) 1 4(+) 4(+)
  3 9 8 3 8 8
  
  
  So the number in 7th row is 398 38 8

• the operations are done in following way:
  1 2 3 4
  
  + 3 4 5 5
  ----------------------------
  4 6 8 9
  ------------------------------
  
  so by striking off any digit from each row we get 3 digit number .Apply same method to get the result at each row .Then again strike off 1 digit from each row to left with 2 digit number and apply same method and so on to get numbers in 7th row...
