EXAMPLE
The 1st digit of the sequence [1] is present in a(1) + a(2) = 1 + 9 = 10;
the 2nd digit of the sequence [9] is present in a(2) + a(3) = 9 + 10 = 19;
the 3rd digit of the sequence [1] is present in a(3) + a(4) = 10 + 2 = 12;
the 4th digit of the sequence [0] is present in a(4) + a(5) = 2 + 8 = 10;
the 5th digit of the sequence [2] is present in a(5) + a(6) = 8 + 4 = 12;
the 6th digit of the sequence [8] is present in a(6) + a(7) = 4 + 14 = 18;
the 7th digit of the sequence [4] is present in a(7) + a(8) = 14 + 20 = 34;
etc.
