Answer:
A. 34; B. 40. D. 88
Step-by-step explanation:
The rule is, "multiply by six and subtract two."
So, if we add two to the number, it should be evenly divisible by 6.
We can check each number.
A. 34 + 2 = 36; 36/6 = 6. TRUE.
B. 40 + 2 = 42; 42/6 = 7. TRUE.
C. 55 + 2 = 57; 57/6 = 9½. False.
D. 88 + 2 = 90; 90/6 = 15. TRUE.
E. 119 + 2 = 121; 121/6 = 20⅙. False.
The numbers that satisfy the rule are 34, 40, and 88.
