Answer:
A = -21
B = -19
C = -13
D = -7
E = -4
Step-by-step explanation:
Looking at the only two numbers provided, and that one space between them, we can only assume that they're being increased by 3. :
-16 + 3 = C
-16 + 3 = -13
-13 + 3 = -10
So we can do the same for all answers except A and B because they're before -16. Instead for A and B, we subtract 3 because they're before -16.
-16 - 3 = B = -19
-19 - 3 = A = -21
-10 + 3 = D = -7
-7 + 3 = E = -4
-21 , -19 , -16 , -13 , -10 , -7 , -4
A B C D E
