suganya says

12 and 15 answer. because 1 and 2 continue and then 2 numbers hide 3 and 4, so 5 next 1 number hide i.e 6 then 7, next 3 numbers hide 8,9,10 and display 11. From this they hide the number in this series 0213. as per this next number is 12 after 2 number should hide 13, 14 and display 15 and then 1 number hide 16, then display 17. the series is 1, 2, 5, 7, 11, 12, 15, 17….
