Given 7 numbers, any polynomial of degree 7 or more can be made to fit.
One possibility here is: 9 14 11 17 13 20 15
This is the merging of two sequences:
the first going 1*3-1, 2*3-1, 3*3-1, ...
and
the second going 1*2+1, 2*2+1, 3*2+1, ...
It all depends on the sequence you are talking about. For example, the next number in the sequence 0,1,1,2,3,5,8,13,_ would be 21. This would be the Fibonacci sequence as the rule is add the 2 previous terms to get the next term. Another example would be this: 11,121,1331,14641,______.The missing number is 161051, following the pattern of powers of 11, 11^1, 11^2, 11^3 and so on. If you understand what I am trying to say, it all depends on the sequence you are trying to find the number in.
11
because you add the first 2 terms and the next tern was the the sum of the first 2 terms.
16
Consecutive terms in the sequence are being divided by -2. Therefore, -1 / -2 = 1/2 or 0.5.

They are: 10 and 16

15 19
Ignoring the "9" , then this is a Fibonacci sequence. 2,2,4,6,10 The first two terms are 'seed' terms then successive terms equal the sum of the two previous terms. 2 + 2 = 4 2 + 4 = 6 4 + 6 = 10 The next term would be 6 + 10 = 16.
2 is the answer
