2,3,5,9,17 what’s the pattern?
The pattern is multiply by 2 then subtract 1
2 x 2 - 1 = 4 - 1 = 3
3 x 2 - 1 = 6 - 1 = 5
5 x 2 - 1 = 10 - 1 = 9
9 x 2 - 1 = 18 - 1 = 17
17 x 2 - 1 = 34 - 1 = 33
33 x 2 - 1 = 66 - 1 = 65
65 x 2 - 1 = 130 - 1 = 129
The total number of articles is 14 and only 7 can be published. Since what is asked is the ways to assemble the 7 articles, this is a permutation problem.
14P7 = <span>17297280 ways
If order is not of concern, the problem is just a combination problem
14C7 = </span><span>3432 ways</span><span />
