According to Wittgenstein's Finite Rule Paradox every finite sequence of numbers can be a described in infinitely many ways and so can be continued any of these ways - some simple, some complicated but all equally valid. Conversely, it is possible to find a rule such that any number of your choice can be the next one.The simplest rule is un = 18 - 3n
29, assuming it is an algebraically reclusive sequence.
18
It probably is 18 because if divided by 2 they are 3, 5, 7, 9, 11 and 13 but 9 is not a prime number
18
What number best completes the sequence 1 1/2 5 10 1/2 18

18
18
The number which best completes the sequence below is:2 9 5 13 10 19 17?
18
1.5 5 10.5 18 25.5
The number which best completes the sequence below is: 2 9 5 13 10 19 17 ?
Continuing the sequence would be the the numbers 24, 31, 39.
18
It is 24+7 = 31
The difference between the numbers is increasing by 2 every time. Therefore, 18 + 9.5 = 27.5 is the next number in the sequence.
