40-0 = 40.
40-9 = 31.
31-0 = 31.
31-9 = 22.
22-0 = 22.
22-9 = 13.
So, the answer,
13-0 = 13.
13-9 = 4.
I thought it's the easy way to solve.
40-0 = 40.
40-9 = 31.
31-0 = 31.
31-9 = 22.
22-0 = 22.
22-9 = 13.
So, the answer,
13-0 = 13.
13-9 = 4.
I thought it's the easy way to solve.

I would think it as, 1st digit decreasing, and 2nd digit increasing by one.
1st digit = 4, 3, 2, 1, 0.
2nd digit = 0, 1, 2, 3, 4.
So series should look like, 40 40 31 31 22 22 13 13 04 04 -15 -15 -26 -26.
1st digit = 4, 3, 2, 1, 0.
2nd digit = 0, 1, 2, 3, 4.
So series should look like, 40 40 31 31 22 22 13 13 04 04 -15 -15 -26 -26.

May be its right.
40-9 = 31.
31-0 = 31.
31-9 = 22.

40-9=31, 31-22=9, 22-9=13 So 13-9=4.
So as the each number is repeated the first number in the pair will be 13 and the second number will be 4.
[13 4].
