Hai ,
This is dhanamma .This is my idea please perdone me if it is wrong.
see the alternate numbers like as above the denominater having odd numbers they are 7 9 11 then the next number is 13.
come to numerator its having 1 4 7 The difference between these numbers is 1-4=3 4-7=3 then 7-?=3 (7-10=3).
so the final answer is 10/13.

substrate each digit of (1) from (3) respectively
you will get 3-0=3, 7-5=2, 10-5=5 ---- i.e (3,2,5) which is the next 3 terms represented as (4).
Now, substrate each digit of (2) from (4) respectively,
