3 - 11 = 8,
11 - 22 = 11,
22 - 36 = 14,
36 - 53 = 17,
So next number will be '53'.
11 - 22 = 11,
22 - 36 = 14,
36 - 53 = 17,
So next number will be '53'.

(42+38)/2 = 40.
(35+31)/2 = 33.
(28+22)/2 = 25.
So 25, 22 might also be the answer.
(35+31)/2 = 33.
(28+22)/2 = 25.
So 25, 22 might also be the answer.

42-2 = 40
40-2 = 38
38-3 = 35
35-2 = 33
33-2 = 31
31-3 = 28
28-2 = 26
26-2 = 24
So the final answer is 26, 24.
40-2 = 38
38-3 = 35
35-2 = 33
33-2 = 31
31-3 = 28
28-2 = 26
26-2 = 24
So the final answer is 26, 24.

42-2 = 40.
40-2 = 38.
38-3 = 35(subtract 3 after two numbers).
35-2 = 33.
33-2 = 31.
31-3 = 28(subtract 3 after two numbers).
28-2 = 26.
26-2 = 24.
And our final ans is 26 24.
40-2 = 38.
38-3 = 35(subtract 3 after two numbers).
35-2 = 33.
33-2 = 31.
31-3 = 28(subtract 3 after two numbers).
28-2 = 26.
26-2 = 24.
And our final ans is 26 24.

40 42 38 difference -2.
35 33 31 difference -2.
28 (-2) 26 (-2) 24.
Then answer is 26 24.
35 33 31 difference -2.
28 (-2) 26 (-2) 24.
Then answer is 26 24.

Hai sari, 1027, 1031, 1037, 1045, 1054, ...
1027 +(4)+ 1031 +(6)+ 1037 +(8)+ 1045 +(9)+ 1054..
It is an alternative adding series but PRIME NUMBERS are not allowed (prime numbers: 2 3 5 7 11 13 17 19 23).
So it followed: 4 6 8 9 10 ...
Then 1027 +(4)+ 1031 +(6)+ 1037 +(8)+ 1045 +(9)+ 1054....
1054+(10) = 1064.
1027 +(4)+ 1031 +(6)+ 1037 +(8)+ 1045 +(9)+ 1054..
