To write "55th" in words, you would write it as "fifty-fifth." This follows the standard English convention for ordinal numbers, where numbers are written out as words when indicating their position in a sequence.
Well, by definition a "random number sequence" is random; i.e. you cannot find out the next term.However if you're just trying to find the formula for a "number sequence" (not random):1) look at what you have to do to get from one number in the sequence to the next - example the initial difference between the numbers may give a sequence such as "+4, +6, +8, +10", this then gives a sequence of "+2, +2, +2 etc." - this does help to to find out the formula for the sequence.2) write down the "term numbers" (call this "t") above or below the sequance, (i.e. 1st term, 2nd term etc.) and see what you have to do to get from the term number to the sequence number. i.e "3t-1", "t squared minus 3" etc.

How do you write thirty-one million in numbers
It is already written in numbers.
It is possible if you define some arbitrary sequence, to decide which number comes "after" which other number. There is no "natural" sequence, as in the case of integers; to be more precise, you can't use the ordering defined by the "less-than" operator as such a sequence: between any two different rational numbers, there are additional rational numbers.
1, 4, 7, 10, 13, …
You do nothing! A sequence of numbers will contain no X and so nothing needs doing!

A sequence is just an ordered set of events. You write it by telling what happened in order.
The get a list of all even numbers, write the number 2, then slip the next number (3) and write the number 4. Continue by skipping every other number, which will be the odd numbers. Alternatively, write a consecutive list of all of the numbers from 1 to 50, then multiply each one by 2. The products are all of the multiples of 2, which are even numbers.
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)

To write out 6.4 million in numbers including the zeros, you would write it as 6,400,000. This is because the number 6.4 million consists of 6 million (6,000,000) and an additional 400,000 (400,000). Therefore, when written out in numerical form, it becomes 6,400,000.
