Step-by-step explanation:
3/6 - 2/5 = 0.1
4/7 - 3/6 = 0.071
5/8 - 4/7 = 0.053
Since there is no common difference d, the sequence is not arithmetic.
(3/6) / (2/5) = 1.25
(4/7) / (3/6) = 1.14
(5/8) / (4/7) = 1.09
Since there is no common ratio, the sequence is not geometric.
Hence the sequence is neither an AP or GP.
Formula for nth term: (n + 1)/(n + 4).
