They are: 33 29 25 21 17 13 9 a reduction of 4 each time
-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
The series alternates between two sequences: one that increases by 1 (11, 12, 13, 14) and another that increases by 1 as well but starts from 2 (2, 3, 4). Following this pattern, the next number in the increasing sequence would be 15, and the next number in the second sequence would be 5. Therefore, the next numbers in the series would be 15 and 5.

The next two number in the series are: 5 & 16
The sum of the previous two numbers in the series.
-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).
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).
The series alternates between two sequences: one that increases by 1 (11, 12, 13, 14) and another that increases by 1 as well but starts from 2 (2, 3, 4). Following this pattern, the next number in the increasing sequence would be 15, and the next number in the second sequence would be 5. Therefore, the next numbers in the series would be 15 and 5.

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)]
