That'd be the Fibonnaci sequence (this time without the wikipedia URL :P)
If you mean: 1 4 9 16 and 25 then they are square numbers
The sequence 1-123-458-1321 is known as a "look-and-say" sequence. In this type of sequence, each term is derived by describing the digits of the previous term. For example, "one 1" becomes "11," and "two 1s" becomes "21." However, the specific sequence you've provided does not appear to follow this pattern directly, so it may require further context to clarify its nature.
Often when given only a few numbers in a sequence or series, there is more than one possible answer. As a sequence, this could be the numbers NOT divisible by 4. In this case the sequence is 1, 2, 3, 5, 6, 7, 9, 10, 11, 13, 14, 15, 17, 18, 19, 21, 22, 23, 25, 26, 27, 29, 30, 31, 33, 34, 35, 37, 38, 39, 41,... The sequence could be: all numbers n such that 2n + 9 is prime, or it could be all numbers n such that 30(n)+13 is prime, just to name a few.

It is called a Fibonacci number sequence! 1,1,2,3,5,8,13,21...
In the sequence 8549176320 the numbers are arranged alphabetically according to the name of the number.i.e.eightfivefournineonesevensixthreetwozero
It is the square numbers of 1-6, 1,4,9,16,25,36

Michael, begins with last letter of previous word in sequence.
Even numbers.
Ah, what a delightful sequence you have there, friend! That sequence is called the "square numbers sequence." Each number is a perfect square - the result of multiplying a number by itself. Keep exploring the beauty of numbers and patterns, and let your creativity flow like a happy little stream.
Assuming it continues 15, 21, 28, ... then it is the triangular numbers.
