The answer is 6.
because the sequence is all the same numbers, but they are in different number bases.
110= 6 in binary
20= 6 in base 3
12= 6 in base 4
11= 6 in base 5
10= 6 in base 6
all the rest of the numbers in the pattern would be 6, because we passed base 6 and all the other number bases have the digit '6' in them.
One number does not make a sequence (nor a series).

One number does not make a sequence (nor a series).
There is no series of number: just one very large number!
A single number cannot define a sequence, even less a series.

A series is a set of partial sums of sequences of numbers. A single number, such as 135, does cannot define a series.
The number 7 comes next.

It is: 4554
11 comes next.
The number that comes next in the series 1 2 2 5 3 10 is 7. You get this number by subtracting the number 3 from the number 10.
