38-3 = 35.
35-2 = 33.
33-2 = 31.
31-3 = 28
28-2 = 26.
26-2 = 24.
40-2 = 38.
38-3 = 35.
35-2 = 33.
33-2 = 31.
31-3 = 28

Given 42, 40, 38, 35, 33, 31, 28.
Here the difference between 42 and 35 is 7 and 40 and 33 is 7 from above we can say that difference between two numbers having a gap of 2 digits is 7.
By this process, we get answers as 26,24
42-35 = 7.
40-33 = 7.
38-31 = 7.
35-28 = 7.
Now,
33 - 7 = 26.
31 - 7 = 24.
