-57The first two numbers in the series has a difference of 89. The next two numbers (209, 129) has a difference of 80. The next two (129,58) has a difference of 71. As you can see the differences change by 9, so the next two numbers in the series (58, -4) has a difference of 62. Following this pattern, the next two numbers in the series will have a difference of 53. So the next number in this series will be (-4-53 = -57).
the numbers next in series are 35,43,51,... any two consecutive terms has a difference of 8
oNe, tWo, tHree, fOur,fIve,sIx etc. It is the second letter of each consecutive number
The next two number in the series are: 5 & 16
The next number in the series is 36. The series alternates between two patterns: the square of the index (1, 4, 9, 16, etc.) and the index itself (1, 2, 3, 4, etc.). The pattern restarts every 2 indexes.
The sum of the previous two numbers in the series.

A single number, such as 18233039, cannot define a series.
The next number in the series will be 66. The next number is found by adding the two previous numbers. (2+7=9, 9+7=16, etc...)
21. Your example is in the Fibonacci series.
the numbers next in series are 35,43,51,... any two consecutive terms has a difference of 8
This is called a Fibonacci series ( after the mathematician who came up with it).

1Another AnswerEach number of the series appears to double as the series progresses: 1/12 (x2), 1/6 (x2), 1/3 (x2), 2/3, etc. This being so, the next number in the series would be 4/3 or 1-1/3 (2/3 x 2)..
Next in sequence is 13112221.This series describes each number that came before it:1 [One]11 [One One]21 [Two One(s)]1211 [One Two and One One(s)]111221 [One One, One Two, and Two One(s)]312211 [Three One(s), Two Two(s), and One One]The next number in the series is:13112221 [One Three, One One, Two Two(s), Two One(s)]
The next two number in the series are: 5 & 16
