There are infinitely many polynomials of order 4 that will give these as the first four numbers and any one of these could be "the" rule. Short of reading the mind of the person who posed the question, there is no way of determining which of the infinitely many solutions is the "correct" one.
One possible answer, based on a polynomial of order 3, isUn = (-n^3 + 8*n^2 - 10*n + 6)/2 for n = 1, 2, 3...
A number sequence is not a question. So there can be no "answer".
A single number, such as 2726101400 does not define a sequence.
To get the next number in the sequence, you simply multiply by 26*2=1212*2=2424*2=4848*2=96
One numbers, such as 9162433, cannot comprise a sequence.
A single number, such as 4642142824816 does not constitute a sequence.

The number that occurs most in a number sequence.
There is the Morris number sequence and the Fibonacci number sequence. The Padovan sequence. The Juggler sequence. I just know the Fibonacci sequence: 0,1,1,2,3,5,8,13,21,34,55,89,144,233,377 Morris number sequence: 1 11 21 1211 111221 312211...
It is an irrational number; therefore the sequence is endless. The 'full number sequence' can never be known.
What is the the next number in the sequence 1,2,4,7,11,.....
A number sequence is an ordered set of numbers. There can be a rule such that the next number in the sequence can be determined by the values of some or all of the preceding terms in the sequence. However, the sequence for a random walk illustrates that such a rule is not necessary to define a sequence.
17298 is a single number, not a sequence - or squence even.17298 is a single number, not a sequence - or squence even.17298 is a single number, not a sequence - or squence even.17298 is a single number, not a sequence - or squence even.
There is no sequence for a single number.
-2 is a single number. A single number is not sufficient to define a sequence.
381838 is one number: it does not describe a sequence.
A single number, such as 171422, does not constitute a sequence.
The 16th number of the Fibonacci sequence is 987.
