The 1's alternate between being a numerator and denominator.


The other number is basically the series of prime numbers, starting from 2.

2,3,5,7,11,13,17,19,....


So the next two in the pattern would be :

13/1 , 1/17

The numerator is the same series of prime numbers.


The denominator are ascending powers of 2.

2 = 2¹
4 = 2² = 2 × 2
8 = 2³ = 2 × 2 × 2
16 = 2⁴ = 2 × 2 × 2 × 2
32 = 2⁵ = 2 × 2× 2 × 2 × 2

Basically, keep multiplying by 2.

So the next two in the pattern are :


13/64 and 17/128
