Logical Reasoning - Number Series - Discussion
Discussion Forum : Number Series - Type 3 (Q.No. 15)
Directions to Solve
Look carefully for the pattern, and then choose which pair of numbers comes next.
15.
16 26 56 36 46 68 56
Answer: Option
Explanation:
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.

26 - 16 = 10
68 - 56 = 12(after two nos.)
46 - 36 = 10
80 - 68 = 12
66 - 56 = 10.
Hope you understand.

Let's assume the two unknown numbers be x and y respectively.
16 26 56 36 46 68 56 x y.
Let (in sequence)
[ 16 26 56 ] be series (a)
[36 46 68 ] be series (b) and
[56 x y ] be series (c).
Now substrate (b-a)
36 46 68 ------> (b)
16 26 56 -------> (a)
i.e = 20 20 12 ------> (i)
{These are the difference between a and b series}
Now, add the difference (i) with (b)
36 46 68 ------> (b)
20 20 12-------> (i)
=56 66 80 (answer)
x = 66,
y = 80.
16 26 56 36 46 68 56 x y.
Let (in sequence)
[ 16 26 56 ] be series (a)
[36 46 68 ] be series (b) and
[56 x y ] be series (c).
Now substrate (b-a)
36 46 68 ------> (b)
16 26 56 -------> (a)
i.e = 20 20 12 ------> (i)
{These are the difference between a and b series}
Now, add the difference (i) with (b)
36 46 68 ------> (b)
20 20 12-------> (i)
=56 66 80 (answer)
x = 66,
y = 80.

16+10 = 26,
36+10 = 46,
56+10 = 66,
56+12 = 68,
68+12 = 80,
Ans: 66 80.
36+10 = 46,
56+10 = 66,
56+12 = 68,
68+12 = 80,
Ans: 66 80.

1st & 2nd numbers = 16, 26.
Then
4th & 5th numbes = 36, 46.
Then as per the series repeated,
7th & 8th = 56,[ 66].
Now,
After the first 2 numbers = 56.
Again after 2 numbers = 56 + 12 = 68.
As per series = 68 + 12 = [80].
According to logic answer is,
[66,80].
Hope this is helpful.
