It would contain of all the number from 1000 to 9998 leaving 9 numbers.
There are infinitely many possible number sequences, and infinitely many numbers which can appear in those sequences. Any and every number can appear in a number sequence.
Question is not very clear about the context of word 'sequence' here. If I am to select 4 numbers out of four and arrange them in order then there are 4!*8C4 = 1680 different sequences possible. If the word sequence refers to some arithmetic sequence or geometric sequence, then counting is going to change for sure.
If there's a repeating sequence then it's a rational number.
A few examples: Counting numbers are an arithmetic sequence. Radioactive decay, (uncontrolled) bacterial growth follow geometric sequences. The Fibonacci sequence is widespread in nature.
A sequence of seven numbers is a set of numbers arranged in a specific order. Each number in the sequence is called a term. For example, a sequence of seven numbers could be {1, 3, 5, 7, 9, 11, 13}, where each term differs by a constant value of 2. Sequences can follow different patterns, such as arithmetic sequences where each term is found by adding a constant value to the previous term, or geometric sequences where each term is found by multiplying the previous term by a constant value.

A numerical sequence is a set of ordered numbers. That is all! For example, stochastic sequences are random.
If there's a repeating sequence then it's a rational number.
if repeating is allowed... 36 (6x6, for the last two digits) If not, 6 (3x2, last two digits)

A group of numbers in order. Usually, when talking about sequences, people talk about infinite sequences: a sequence that never ends (it has a first number, a second number, and an Nth number for any N, with no last number). There's no restriction of what the numbers are - they can be anything, and don't have to follow any pattern. But in practice, if you want to talk about a specific sequence, you'd need some rule for calculating the numbers in it. For example, you could have the sequence whose Nth term is 1/N. Sometimes sequences are taken to start with a 0th term rather than a first term. This is a question of notation, and doesn't really change anything about how sequences work. You can also think of a sequence as a function from the natural numbers {1,2,3,...} or {0,1,2,3,...} to whatever the sequence is of (usually real numbers, or sometimes complex numbers). For this reason, sequences are also called arithmetical functions. The most common way to write the nth term of a sequence is an (for one sequence; if you need to talk about more sequences, you'd write bn or cn)
A repeating sequence of numbers ! The digits 123456789 are simply repeated over and over.
Fibonacci sequence is when you add the two previous numbers together 1,1,2,3,5,8 ect
1.the following of one thing after another; succession.
