if repeating is allowed... 36 (6x6, for the last two digits) If not, 6 (3x2, last two digits)
the numbers 0 through 9 written in sequence or any portion of that sequence
Not sure what it is you are asking here. Sequence of numbers? names? prime numbers?
It is the Fibonacci sequence. Whereby each number is the sum of the preceding two numbers. The next digits are 13(5+8) 21 (13+8)etc.
Assuming you mean permutations of three digits, then the set of numbers that can be made with these digits is: 345 354 435 453 534 543 There are six possible permutations of three numbers.
10 digits to select for the first number in the sequence 10 digits to select for the second number in the sequence for each possible option of 10 digits in the first slot in the sequence (10 * 10) 10 digits to select for the third number in the sequence for each possible option of 10 digits in the second slot for each possible digit in the first slot of the sequence (or more easily put, 10 possible digits for each of 100 potential first two number sequences) [10*10*10] etc.... =10 * 10 * 10 * 10 * 10 * 10 * 10 = 10^7 = 10,000,000 (10 Million) Now add an area code before that 7 digit phone number and you get 10 Billion combinations (of course there are exclusions such as any sequence starting in 911 would be prohibited which is a reduction of 10 million numbers itself - 911 000 0001, 911 000 0002, etc. There are many other exclusions as well such as can't start with 0 - this removes another 1 billion sequences)
The one closest to the Middle if your sequence is of an even set of digits. The median will be a specific number if you have a sequence of odd digits.

Infinite. If numbers can be repeated, the list could go on nonstop.
In numerology, any repeating sequence of numbers is a good sign. In cursory research, the term 'angel numbers' came up quite a bit. In angelology, the sequence of numbers, especially the number 7, in digits of three or more is considered to be very lucky.
A repeating sequence of numbers ! The digits 123456789 are simply repeated over and over.

if the repetition is not allowed then the arrangement can be 3*2*1 = 6 ways if repetition is allowed the ways can be 6*6*6= 216 ways
There's no way to answer. Serial numbers can have as few as 2 digits or as many as 20 ! It depends entirely on what the sequence is indicating.
9631. The sequence consists of the prime numbers which, when their digits are reversed, are perfect squares.
The one I examined had 6 digits, however, there WILL be variations from that depending on when it was made.
