Lucas sequences are sequences of numbers which are defined by two seeds: U(1) and U(2); and an iteration rule: U(n+2) = U(n) + U(n+1) for n = 1, 2, 3, ...
When the two seeds are both 1, the sequence is the well known Fibonacci sequence.
The lucas numbers are a sequence of numbers. They go as 1, 3, 4, 7, 11, 18 etc the sequence is bery similar to the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13)
A sequence.
They are a sequence of numbers and each sequence has a term number.
A numeric sequence is a list of numbers in a particular order. A non-numeric sequence is an ordered list of something other than numbers.
Goemetric sequence : A sequence is a goemetric sequence if an/an-1is the same non-zero number for all natural numbers greater than 1. Arithmetic sequence : A sequence {an} is an arithmetic sequence if an-an-1 is the same number for all natural numbers greater than 1.

There are no numbers before the sequence!
The next number is 47. After this series gets going, each number is the sum of the two numbers before it. If the first two numbers were zero and 1, this would be the Fibonacci series.
A sequence.
This is called a sequence and if we add the numbers in that sequence it is called a series.
To count a triplet in a sequence of numbers, look for three consecutive numbers that are the same. Count how many times this pattern occurs in the sequence.
An arithmetic sequence is a list of numbers which follow a rule. A series is the sum of a sequence of numbers.
Arithmetic Sequence
They are a sequence of numbers and each sequence has a term number.
Its indefinite: Start with 0,1 add last two numbers = 1 add to sequence = 0,1,1 add last two numbers = 2 add to sequence = 0,1,1,2 add last two numbers = 3 add to sequence = 0,1,1,2,3 add last two numbers = 5 add to sequence = 0,1,1,2,3,5 add last two numbers ......... add to sequence ..........
The number of inversions in a sequence of numbers is the count of pairs of elements that are out of order.
