Answer:
A. 28, 34, 40
Explanation:
In order to solve this you just have to follow the steps given, the start of the pattern is 28 and after that you add 6 to the previous number, so you know that the second number would be 28+6 that would be 34, and the third number after 34 would be 40.
So the first three numbers would be 28, 34, 40.
