As we can see the positive integer 9 is being added to every number to get it's succeeding term .
Then ,
-11 + 9 = -2
-2 + 9 = 7
7 + 9 = 16
Now , using the same pattern let us find the forthcoming terms .
16 + 9 = 25
25 + 9 = 34
34 + 9 = 43
Therefore , the next three terms of the sequence :
-11 , -2 , 7 , 16 , 25 , 34 , 43 .
