Any number that you choose can be the next number. It is easy to find a rule based on a polynomial of order 5 such that the first five numbers are as listed in the question followed by the chosen next number. There are also non-polynomial solutions. Short of reading the mind of the person who posed the question, there is no way of determining which of the infinitely many solutions is the "correct" one.
If you want it to be 1, use the following rule:
t(n) = (n^5 - 15*n^4 + 85*n^3 - 225*n^2 + 218*n - 104)/8
If you want the next number to be 100, use
t(n) = (19*n^5- 285*n^4 + 1615*n^3 - 4275*n^2 + 5066*n - 1720)/20
In this particular case, the answer is probably based on the linear rule,
t(n) = -7n + 28, and if that is the case, the next number is -14.

n - 1
7 - 4n where n denotes the nth term and n starting with 0
n-9+3
Well, darling, the nth term for the sequence 18, 12, 6, 0, -6 is -6n + 24. So, if you plug in n = 1, you get 18; n = 2 gives you 12, and so on. Just a little math magic for you to enjoy!

0
n - 1
7 - 4n where n denotes the nth term and n starting with 0
If the nth term is 8 -2n then the 1st four terms are 6, 4, 2, 0 and -32 is the 20th term number
n-9+3
-4, -3, 0, 5, 12, 21, 32

You can see that you add 10 to the previous term to get the next term. Term number 1 2 3 4 Term 4 14 24 34 You can also say: Term number 1 2 3 4 Term 0*10+4 1*10+4 2*10+4 3*10+4 So the nth term would be 10(n-1)+4 Or if you expand it, it's 10n-6
This is the Fibonacci sequence, where the number is the sum of the two preceding numbers. The nth term is the (n-1)th term added to (n-2)th term
16 - 4nor4 (4 - n)
nth term can be calculated from the formula (n - 1) x n/2.Eg 8th term = 7 x 4 ie 28; 42nd term = 41 x 21 ie 861.If the series starts at 1 rather than 0, the formula is (n + 1) x n/2If you are satisfied with this reply please consider awarding a Recommended Point to the responder.A:(n2-n) ÷ 2
