here is the logic out. this series goes out in alternate numbers i.e, 1,7,19 on one part and 4,16,40 on other part
the first part logic is 1) 1 plus 6 gives 7
2) 7 plus (6+6) gives 19
3) 19 plus (6+6+6) gives 37
the second part logic is 1) 4 plus 12 gives 16
2) 16 plus (12+12) gives 40
3) 40 plus (12+12+12) gives 76
so the third step in both parts are the answers hence the missing numbers are 37,76. so series goes as follows 1,4,7,16,19,40,37,76
