My way of approach was,
8*2 = 16 + 6 = 22
8*3 = 24 + 4 = 28
8*4 = 32 + 2 = 34
Hope this is good.
8*2 = 16 + 6 = 22
8*3 = 24 + 4 = 28
8*4 = 32 + 2 = 34
Hope this is good.

8 is placed alternatively and added 6. So the answer is 34.

22 + 6 = 28,
28 + 6 = 34.
28 + 6 = 34.

Rule : Add 6 to the alternate numbers except the 8 because it is a constant random number.

6 and 8 are common here (28 - 22 = 6). Find the difference between the first two numbers i.e. 22 - 8 = 14. The sum of the difference i.e 14 + the sum of the two common numbers i.e 6 + 8 gives 28, that is it.
28 - 8 = 20; 6 + 8 + 20 = 34,
34 - 8 = 26; 6 + 8 + 26 = 40,
40 - 8 = 32; 6 + 8 + 32 = 46.
28 - 8 = 20; 6 + 8 + 20 = 34,
34 - 8 = 26; 6 + 8 + 26 = 40,
40 - 8 = 32; 6 + 8 + 32 = 46.

According to me,
22 + 8 = 30.
30 - 2 = 28.
28 + 8 = 36.
36 - 2 = 34.
22 + 8 = 30.
30 - 2 = 28.
28 + 8 = 36.
36 - 2 = 34.
