Let's observe the diference between the terms:
32 - 20 = 12
42 - 32 = 10
50 - 42 = 8
56 - 50 = 6
As can be observing, the terms are increasing in the rates: 12, 10, 8, 6, ...
The following term increases 2 units less than the previous term had increased.
The next term will increase in 4 units:
56 + 4 = 60.
And the other term will increase in 2 units:
60 + 2 = 62.
Answer:
60, 62.
