4 8 22 12 16 22 20 24.
Solution is correct: i.e 22,28 they are asking the next pair so 22 is one of them for sure.
Now:
Solution is work like this:---
4, 8, 22, (8+4 = 12), (12+4= 16), 22, (16+4 = 20), (20+4= 24), 22, (24+4= 28).
I hope it helps.
Thank you!

4+8=12.
8+8=16.
22,
12+8=20.
16+8=24.
22,
20+8=28.
So 22, 28 is right.
8+8=16.
22,
12+8=20.
16+8=24.
22,
20+8=28.
So 22, 28 is right.

Increasing multiple and differ 4.
2 8
3 12
4 16
5 20
6 24
7 28
8 32
So 28 and 32.
2 8
3 12
4 16
5 20
6 24
7 28
8 32
So 28 and 32.

@John Ajay- I agree! There is adequate reason for both A and C - both indeed are correct for the simple reason of adding 8. Poor test/answer system if you ask me!

I think the answer is A.
There many assumptions in solving this sum.
But the first thing that stroke me was interpolating 22 and adding 8.
4+8=12.
8+8=16.
12+8=20.
16+8=24.
20+8=28.
And so the answer probably could be 22 28.

4*2 = 8.
4*3 = 12.
4*4 = 16.
4*5 = 20.
4*6 = 24.
4*7 = 28.
4*8 = 32 So answer is 28&32.
4*3 = 12.
4*4 = 16.
4*5 = 20.
4*6 = 24.
4*7 = 28.
4*8 = 32 So answer is 28&32.

Answer,
4+0 = 4.
4+4 = 8.
(22).
8+4 = 12.
12+4 = 16.
(22).
16+4 = 20.
20+4 = 24.
Then first 22.
24+4 = 28 The answer is 22&28.
28+4 = 32.
(22) so on...
4+0 = 4.
4+4 = 8.
(22).
8+4 = 12.
12+4 = 16.
(22).
16+4 = 20.
20+4 = 24.
Then first 22.
24+4 = 28 The answer is 22&28.
28+4 = 32.
(22) so on...
