- Next No. in series is 19161142
First digit in each term of the series is 1, then other digits in the term are obtained by taking the sum of two consecutive digits of the previous term as in term 135,3 and 5 are obtained from 123 as 3 is (1+2) and 5 is (2+3).
In the same way 4 and 8 in the term 148 are obtained from 135 as 4=1+3 and 8=3+5 and so other terms of the series are obtained.
The 19161142 is obtained by taking first digit as 1 and other digits by taking sum of consecutive digits of the term 188311 as 9=1+8, 16=8+8,11=8+3, 4=3+1 and 2=1+1.
