There can be no sensible answer to this question. It mentions "numbers" and then lists only one number! One number is different from numbers!
It is not possible to answer the question since a single number, such as 1266918, does not make a sequence. Also, there is no simple partitioning of the given number into a set of numbers which make up a straightforward sequence.
A series is a set of partial sums of sequences of numbers. A single number, such as 135, does cannot define a series.
order the numbers least to greatest and the median number is in the middle
That's called the average.

To complete the series 49 7 9 3 64 8 25 ? the question mark would be replaced with a 5. The second number in each pair is the positive square root of the first.
The sum of the numbers divided by the number of numbers.
The factorization of a number is a series of numbers that make that number 
There is no series of number: just one very large number!
It is a set of numbers derived from a sequence. The first number in the series is the first number of the sequence. The second number in the series is the sum of the first two numbers of the sequence. The third number in the series is the sum of the first three numbers of the sequence. and so on. Mathematically, a series is easily defined using the sigma notation but that, unfortunately, is beyond the scope of this browser.
The sum of the previous two numbers in the series.
Median

You'll have to separate those numbers with spaces. There's no way to tell what numbers are in the series--it's just one long number.
No, it is literally impossible. An equations is a question with a series of numbers which communicate by dividing, subtracting, adding, or multiplying. If we have no end to these numbers, there is an endless wave of equations coming at us, using the new number, and the infinite number before it, and after it.
First series of numbers are the number of wins. The second series of numbers is loses. and the Third series of numbers is Ties. (Wins-Losses-Ties)
