Logical Reasoning - Number Series - Discussion
Discussion Forum : Number Series - Type 2 (Q.No. 8)
Directions to Solve
Look carefully for the pattern, and then choose which pair of numbers comes next.
8.
6 20 8 14 10 8 12
Answer: Option
Explanation:
This is an alternating addition and subtraction series. In the first pattern, 2 is added to each number to arrive at the next; in the alternate pattern, 6 is subtracted from each number to arrive at the next.

6 20 8 14 10 8 12
6 + 2 = 8
8 + 2 = 10
10 + 2 = 12
12+2 = 14 ( But before 14, you should consider the alternative pattern as well between 12 and 14, which follows the explanation below)
20 - 6 = 14
14 - 6 = 8
8 - 6 = 2
So between 12 and 14, the alternate pattern 2 will come, so the answer is 2, 14.
6 + 2 = 8
8 + 2 = 10
10 + 2 = 12
12+2 = 14 ( But before 14, you should consider the alternative pattern as well between 12 and 14, which follows the explanation below)
20 - 6 = 14
14 - 6 = 8
8 - 6 = 2
So between 12 and 14, the alternate pattern 2 will come, so the answer is 2, 14.

The logic is;
6, 8, 10, 12, 14. Is in even positions. Add +2.
20, 14, 8, 2. Is in odd positions. So, Sub-6.
6, 8, 10, 12, 14. Is in even positions. Add +2.
20, 14, 8, 2. Is in odd positions. So, Sub-6.

It's really confusing series, but we take even series in increasing and decreasing order separately.
Even series taken in increasing order 6 8 10 12.
Even series taken in decreasing order 20 14 8.
We see that increasing series increases by 2 and decreasing series decreases by 6. So the last two digit will be 14 in increasing series and 2 will be in decreasing series.
Even series taken in increasing order 6 8 10 12.
Even series taken in decreasing order 20 14 8.
We see that increasing series increases by 2 and decreasing series decreases by 6. So the last two digit will be 14 in increasing series and 2 will be in decreasing series.

6 20 8 14 10 8 12 2 14.
1) 20-6 = 14.
14-6 = 8.
8-6 = 2.
2) 6+2 = 8.
8+2 = 10.
10+2 = 12.
12+2 = 14.
1) 20-6 = 14.
14-6 = 8.
8-6 = 2.
2) 6+2 = 8.
8+2 = 10.
10+2 = 12.
12+2 = 14.

Hey nothing to worry. Its very simple.
Adding two with odd positioned numbers.
Subtracting six by even positioned numbers.
