Break the series as below
22, 19.5, 21.45 | 33, 30.5, 33.55 | 44, 41.5 , ?
=> 22 , 33, 44
=> 19.5 , 19.5 + 11 , (19.5 + 11*2)
=> 21.45 , (21.45 + 12.1) , (21.45 + 2*12.1)
=> 21.45 + 2 * 12.1 = 45.65

Explanation:

Break the series as below
9,12,4,8 | 12,15,5,9 | 3,6,2,6 | 6,9,?,?
9+3=12/3=4+4=8
12+3=15/3=5+4=9
6+3=9/3=3+4=7
Add 3 to 1st digit than divide 3 to 2nd digit than add 4 to 3rd digit.
So, 3 and 7
