Answer:
D 34, 33
Step-by-step explanation:
Looking at the data set: 3, 6, 5, 10, 9, 18, 17... first try to compare each number using addition, subtraction, multiplication or division:
3 6 5 10 9 18 17
x2 -1 x2 -1 x2 -1
So, it looks like the pattern is first a multiplication by two and then a subtraction of one. If we continue the pattern from 17:
17 x 2 = 34
34 - 1 = 33
So, the next two terms would be 34, 33 (D).
