Q: Look carefully for the pattern, and then choose which pair of numbers comes next. 3 8 10 15 17 22 24
Solution: This is an alternating addition series that adds 5, then 2, then 5, and so on.
Q: 4 7 26 10 13 20 16
Solution: Two patterns alternate here, with every third number following the alternate pattern. In the main series, beginning with 4, 3 is added to each number to arrive at the next. In the alternating series, beginning with 26, 6 is subtracted from each number to arrive at the next.
Q: 32 29 26 23 20 17 14
Solution: In this simple subtraction series, the numbers decrease by 3.
Q: 16 26 56 36 46 68 56
Solution: Here, every third number follows a different pattern from the main series. In the main series, beginning with 16, 10 is added to each number to arrive at the next. In the alternating series, beginning with 56, 12 is added to each number to arrive at the next.
Q: 2 44 4 41 6 38 8
Solution: Here, there are two alternating patterns, one addition and one subtraction. The first starts with 2 and increases by 2; the second starts with 44 and decreases by 3.
Q: 17 32 19 29 21 26 23
Solution: Here, there are two alternating patterns. The first begins with 17 and adds 2; the second begins with 32 and subtracts 3.
Q: 17 14 14 11 11 8 8
Solution: In this simple subtraction with repetition series, each number is repeated, then 3 is subtracted to give the next number, which is then repeated, and so on.
Q: 10 34 12 31 14 28 16
