We look at the set as [11 16] [21 26] [31 36] 41 in this view we get understanding as 11+5=16, 21+5=26, 31+5=36 so 41+5=46, so the first number is 46.
Now place this number in the set 11 16 21 26 31 36 41 46.
Now change the view - 11 [16 21] [26 31] [36 41] 46.
So we get the understanding as - 16+5=21, 26+5=31, 36+5=41 so 46+5=5.
So the numbers are [46,51].

Q. 11, 16, 21, 26, 31, 36, 37, ..... What numbers should come next?
a1 a2 a3 a4 a5 a6 a7 a8 a9
11 16 21 26 31 36 37 (?) (?)
a1-a2=11-16=-5
a2-a3=16-21=-5
a3-a4=21-26=-5
a4-a5=26-31=-5
a5-a6=31-36=-5
a6-a7=36-41=-5
So, a7-a8*=41-46*=-5
a8-a9*=46-51*=-5
Ans: Next numbers are to be, a8*=46* and a9*=51*. Please select it.

11 16 21 26 31 36 41 ? ?
First pattern number is 11 21 31 41 ( adding 10)
11 + 10 = 21
21 + 10 = 31
31 = 10 = 41
41 = 10 = 51 is answer.
Then,
Second pattern number is 16 26 36 (adding 10).
16 + 10 = 26
26 + 10 = 36
36 + 10 = 46 is answer.

Q: 11 16 21 26 31 36 41 ? ?
11 + 5 = 16.
16 + 5 = 21.
21 + 5 = 26.
26 + 5 = 31.
31 + 5 = 36.
36 + 5 = 41.
41 + 5 = 46.
46 + 5 = 51.
Therefore, the answer is 46 51
11 + 5 = 16.
16 + 5 = 21.
21 + 5 = 26.
26 + 5 = 31.
31 + 5 = 36.
36 + 5 = 41.
41 + 5 = 46.
46 + 5 = 51.
Therefore, the answer is 46 51

Another way is : 11, 21, 31, 41 add +10 the next number is 51.
16, 26, 36 add +10 then the next number is 46.
Ans: 46, 51.
16, 26, 36 add +10 then the next number is 46.
Ans: 46, 51.

Here, the logic is that each even and odd number is (+10) from the previous numbers.
