Next numbers will be: 24, 19.
Explanation:
(48, 49, 57, 59)(36, 39, 28, 32),(x,y)
Fist number decreasing by 12 so x = 24
if u observe the difference of consecutive terms:
49-48=1
59-57=2
39-36=3
32-28=4
29-24=5 and so on..

group the elements in to two
Odd Group: 48 57 36 28
Even Group: 49 59 39 32

see the first digit of the odd group numbers
it is, 4,5,3,2 so the first digit for the next number should be 1

now see the second digits of the odd group numbers
_8, _7, _6, again _8 so the next number should have the second digit as 7

so the next number should be 17
