It is the number 9.
number
They are a sequence of numbers and each sequence has a term number.
5
It is a valid sequence which is fundamental to arithmetic since its partial sums define the counting numbers.
after -9 it is -15 then -21, -27 and the ninth is -36
The 9th term of the Fibonacci Sequence is 34Fibonacci Sequence up to the 15th term:1123581321345589144233377610

The counting sequence is making increments of 11,that is, the n-th term will = 11 x nn = 12,t = 12 x 11= 132

The sequence you provided is a "look-and-say" sequence. Each term describes the previous term by counting consecutive digits. The last term, 111221, can be described as "three 1s, two 2s, and one 1," which translates to the next term: 312211.
after -9 it is -15 then -21, -27 and the ninth is -36
1 3 5 8 20 18 10
Calculate the constant difference: e.g. 21,17,13,9,5,1,... The difference is -4. Subtract that difference from the first term. 21 - -4 = 25 The 0th term is 25.
In mathematics, a sequence term refers to an individual element or value within a sequence, which is an ordered list of numbers. Each term in a sequence is typically identified by its position, often denoted as (a_n), where (n) represents the term's index. For example, in the sequence 2, 4, 6, 8, the first term is 2, the second term is 4, and so on. Sequences can be finite or infinite and can follow specific patterns or rules.
