here's the pattern, flip each number around

so

31, 62, 93, 25, 56, 87

becomes

13, 26, 36, 52, 65, 78

the pattern for this is

a(n) = 13n

so the next 2 numbers are 91 and 104

but for us

ANS : 19 and 401

20,51,82

If you notice the first 3 #s are 31,2(1) and 3(31)
the beginning of the second # is 6 and the next 3 numbers are the first three less 6 or 31-6,62-6,93-6
or 25,56,87
the beginning of the second # is 5 so the next 3 numbers are the those less 5 or 25 - 5, 56 - 5, and 87 - 5

19 and 40
31-25=6 25-6=19
19+31=40
three different groups of numbers the first number is 6 less than the previous string....then they all increase by 31 after
