Any help would be greatly appreciate! I have been stuck on this problem for about an hour. It's the last one and the most difficult! First differences are not constant, neither are the second differences or ratios. I'm confused as to how I'm supposed to tackle this problem.

If it were me, I would write the Prime Factorization of all the Denominators. This may lead to something obvious.

@tkhunny  Am I supposed to figure out the least common denominator between all of them?

@tkhunny  1/2: 2 x 1 , 1/4: 2 x 2 , 1/6,: 3 x 2, 1/8: 4 x 2; 2 x 2 x 2, 1/10: 5 x 2 I do see a pattern here! :)

well, 2 = 2*1 4 = 3*2 6 = 2*n ... so 1/(2n) there's not much else I can say except the pattern is obvious

@jdoe0001  I suggest using imgur for that. I don't want you to get in trouble for posting irrelevant information on an already closed question!
