It must be 81 because 9 squared is 81 and 9 is not a prime number whereas the other numbers are squared prime numbers.
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.
All three numbers belong to the sequence:Un = n^2 + n + 8 for n = 1, 2, 3, ...
The number that doesn't belong in the sequence is 29. This is because all the other numbers are either multiples of 2 or can be obtained by adding 1, 2, 3, 4, or 5 to the previous number. In contrast, 29 does not follow this pattern and disrupts the sequence.
They are a sequence of numbers and each sequence has a term number.
Yes, 21 is a number in the Fibonacci sequence. Numbers are usually found by adding up 2 numbers.

The 9th number in the Fibonacci Sequence is 34, and the 10th number in the Fibonacci sequence is 89.
The number of inversions in a sequence of numbers is the count of pairs of elements that are out of order.
A single number, such as 172516261546 does not represent a sequence.
A geometric sequence is an ordered set of numbers such that (after the first number) the ratio between any number and its predecessor is a constant.
Dodging numbers may be missing numbers in a sequence. For example, the underscore in the following sequence represents such a number: 2, 4, _ , 8, 10.
A recursive sequence uses previous numbers to find the next number in a sequence after the base case. The Fibonacci sequence is an example of such a sequence. The base numbers of the Fibonacci sequence are 0 and 1. After that base, you find the next number in the sequence by adding the two previous numbers. So, the Fibonacci sequence looks like so: 0, 1, 1, 2, 3, 5, 8.... So, the third number is found by adding the first and second numbers, 0 and 1. So the third number is 1. The fourth number is found by adding the second and third numbers, 1 and 1. So, the fourth number is 2. You can continue on this way forever.
