Question:
17 17 34 20 20 31 23

Option A):
26 23
Option B):
23 33
Option C):
23 28
Option D):
27 28
Option E):
34 20

Correct Answer is Option C):
23 28

Explanation:
This is an alternating subtraction series with repetition. There are two different patterns here. In the first, a number repeats itself; then 3 is added to that number to arrive at the next number, which also repeats. This gives the series 17, 17, 20, 20, 23, and so on. Every third number follows a second pattern, in which 3 is subtracted from each number to arrive at the next: 34, 31, 28.
