Direction: Look carefully for the pattern, and then choose which pair of numbers comes next. Note also that you will be choosing from five options instead of four.

Correct Option: E
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.
