I calculate it this way: if every other item is short of one, 3 and 1 1 short of 8; 2 and 14 is12; The difference between 12 and 8 is 4, so the difference can be increased by 4, so the difference between 1 1 and the next item should be 16, so11+16 = 27;

There is another online way:

3 = 1^2 +2

2 = 2^2 -2

1 1= 3^2 +2

14= 4^2 -2

(27)=5^2 +2

34= 6^2 -2

2. The original formula is:11,2/4,6/11,17/29,46/76.

It can be seen that the numerator of the second term is the numerator+denominator of the previous term, and the denominator is the denominator of the previous term+own numerator+1.

So the answer is: 122/ 199.
