There are infinitely polynomials of order 3 that will give these as the first three numbers and any one of these could be "the" rule. There are also non-polynomial solutions. 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.
For example,
t(n) = (-7n^3 + 42n^2 - 65n + 36)/6 gives the sequence 1, 3, 5, 0, ...
t(n) = -1n^3 + 6n^2 - 9n + 5 gives the sequence 1, 3, 5, 1, ...
t(n) = (-1n^3 + 6n^2 - 5n + 3)/3 gives the sequence 1, 3, 5, 5, ...
t(n) = (31n^3 - 186n^2 + 345n - 188)/2 gives the sequence 1, 3, 5, 100, ...
Each one is a valid answer!
The simplest solution, based on a polynomial or order 1 is
t(n) = 2n - 1 for n = 1, 2, 3

The number which best completes the sequence below is1 1 3 2 4 6 5 25?
The number which best completes the sequence below is:1 1 3 2 4 6 5 25 ?
What is the missing number in the sequence shown below 1 2 3 5 13 21?
The sequence is 1,2,3,5,8,13,21.......8 is the missing number. This is known as a Fibonacci Sequence. The first two numbers are supplied and then further numbers in the sequence are formed from the sum of the two prior numbers. 3 = 1 + 2 5 = 2 + 3 8 = 3 + 5.....and so on.
What is the next number in this sequence 1 1 2 3 5?
Each number is being added to the one before it. So, 5+3=8. 8 is the next number.
What number best completes the sequence 7 1 5 - 3 7?

What is the number between 1 and 5?
In a number sequence, the number between 1 and 5 is 3.
What is the following number to this sequence 2 5 5 4 5 6 3 7?
The next number in the sequence is 6. The sequence alternates between adding 3 and subtracting 1 from the previous number.
What is the fibinicci sequence?
The Fibonacci sequence is a sequence of numbers where each number in the sequence is the sum of the two numbers right before it. for example: 11235812 <-------Fibonacci Sequence 1 1+1=2 1+2=3 2+3=5 3+5=8 5+8=12
What is the first number over 100 in the following sequence 1 1 2 3 5 8 13 21?
144 The sequence goes by adding the number plus the number before it to get the next number: 1+1=2 1+2=3 2+3=5 3+5=8...
Which number is next in this sequence 1 1 2 3 5?
1+1=2 : 1+2=3 : 2+3=5 : 3+5=8Therefore the next number is 8
