Respuesta :
I think the rule is +12, -4.
-9 , 3, -1
-9 + 12 = 3
3 - 4 = -1
The next two terms in the sequence would be 11, 7.
-1 + 12 = 11
11 - 4 = 7
The sequence would then be:
-9, 3, -1, 11, 7
-9 , 3, -1
-9 + 12 = 3
3 - 4 = -1
The next two terms in the sequence would be 11, 7.
-1 + 12 = 11
11 - 4 = 7
The sequence would then be:
-9, 3, -1, 11, 7
