Sequence 1 / 5, 2 / 8, 4 / 11, 8 / 14 A formula of

Look at all the molecules separately: 1, 2, 4, 8
This is an equal ratio sequence with 1 as the first term and 2 as the common ratio. The general term is the (n-1) power of 2
Look at all the denominators: 5, 8, 11, 14
This is an arithmetic sequence with 5 as the first term and 3 as the tolerance. The general term is: 5 + (n-1) * 3 = 3N + 2
Therefore, the general formula of this sequence is: the (n-1) power of 2 / (3N + 2)
