- the digits in the numbers are considered individually. for eg,in 31 3 and 1 are incremented by 2 individually to get 5 an 3 which is 53. taking 119, 11 is obtained from 9 and 9 from 7 of number 97. incrementing individually, 11 becomes 13 and 9 becomes 11 thus making a number 1311. hence 141 is wrong in the above given sequence
