There are infinitely many possible number sequences, and infinitely many numbers which can appear in those sequences. Any and every number can appear in a number sequence.
Every next number is increased by 5. The next number in the sequence is 23.
common difference is the difference in every two consecutive numbers in the sequence .. or in the other way around, its the number added to a number that resulted to the next number of the sequence ..
Every third number in the Fibonacci sequence is even. This pattern arises because the Fibonacci sequence alternates between odd and even numbers, specifically following the sequence of odd, odd, even. As a result, every third term, starting with the first even number (2), is consistently even: 2, 8, 34, and so on.

Perfect squares.
Arithmetic- the number increases by 10 every term.
The number 5 is a factor of every 5th number in the Fibonacci sequence. This is because every 5th Fibonacci number can be expressed as a linear combination of the Fibonacci numbers preceding it, and the pattern shows that they are all divisible by 5. For example, the 5th Fibonacci number is 5, the 10th is 55, and the 15th is 610, all of which are multiples of 5.
no not every sequence has a formula associated with it.
Double it every time and so the next number will be 80
First 18 terms of the sequence are: 1,1,2,3,5,8,13,21,34,55,89,144,233,377,610,987,1597, 2584. Every third term is 2,8,34,144,610,2584. These are all even so the largest number is likely 2.
The difference between the numbers is increasing by 2 every time. Therefore, 18 + 9.5 = 27.5 is the next number in the sequence.
