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.
Add all the numbers and divide that by the number of numbers.
A number sequence is an ordered set of numbers. There can be a rule such that the next number in the sequence can be determined by the values of some or all of the preceding terms in the sequence. However, the sequence for a random walk illustrates that such a rule is not necessary to define a sequence.
37 because they are increased by consecutive odd numbers each time.
It is 81 because the rest of them are prime numbers squared and 9 is not a prime number because it has more than two factors.

The numbers are increasing by 1,4,9,16,25,36.... which are square numbers so the next increase is 49. Making the next number in the sequence 141
21. This is the Fibonacci series.
From the pattern (n + 4, n + 2, n + ?) I would say the next following number is 20 (n + 1).
A single number, such as 3773949588525642992, does not constitute a sequence.
34. Each number is the sum of the two preceding numbers. This is called the Fibonacci Sequence.
