,5
400, 299,
,97,-4,

Answer 1

1- Ans; 47 , 40 , 33 , 26 , 19 , 12 , 5

2- Ans; 400 , 299 , 198 , 97 , - 4 , - 105

Explanation:

`47 - 40 = 7 \\ 40 - 33 = 7 \\ 5 + 7 = 12 \\ 12 + 7 = 19 \\ 19 + 7 = 26 \\ 26 + 7 = 33`

`400 - 299 = 101 \\ 299 - 101 = 198 \\ 198 - 101 = 97 \\ 97 - 101 = - 4 \\ - 4 - 101 = - 105`
