It is the counter that tells you the position of the numbers in the sequence: the first, second and so on.
-- Start with 0, 1 . -- Each term is then the sum of the two terms before it.
The algebraic expression for the given series of numbers is "2n + 9", where n represents the position of the term.
A sequence is a set of numbers, which are identified by their position in the set. That is to say, there is a function mapping the counting numbers {1, 2, 3, ... } to the set. The counting numbers may include 0. There may or may not be a rule governing the numbers. For example, a random sequence, by definition, should have no rule.
There are infinitely many possible answers. Virtually any function can be made to pass through 2 points. 101, for example, if the sequence is generated by Un = 37*n - 10
It is a sequence of numbers that represents how many spheres you would have in a pyramid of different heights.
It is the counter that tells you the position of the numbers in the sequence: the first, second and so on.
Dodging numbers may be missing numbers in a sequence. For example, the underscore in the following sequence represents such a number: 2, 4, _ , 8, 10.
-- Start with 0, 1 . -- Each term is then the sum of the two terms before it.
It is a sequence of 5 numbers. The numbers could be the start of the sequence generated by the polynomial: Un = (59n4 - 562n3 + 1657n2 - 1442n + 360)/24 for n = 1, 2, 3, ...
The algebraic expression for the given series of numbers is "2n + 9", where n represents the position of the term.

A binary sequence is a sequence of [pseudo-]randomly generated binary digits. There is no definitive sum because the numbers are random. The sum could range from 0 to 64 with a mean sum of 32.
An interval that remains the same throughout a sequence
There are infinitely many possible answers. Virtually any function can be made to pass through 2 points. 101, for example, if the sequence is generated by Un = 37*n - 10
Surrogate Key: Surrogate keys are keys that have no "business" meaning and are solely used to identify a record in the table. Such keys are either database generated (example: Identity in SQL Server, Sequence in Oracle, Sequence/Identity in DB2 UDB etc.) or system generated values (like generated via a table in the schema). Natural Key: Keys are natural if the attribute it represents is used for identification independently of the database schema. What this basically means is that the keys are natural if people use them example: Invoice-Numbers, Tax-Ids, SSN etc.
