Determine whether each sequence is arithmetic, geometric, or neither. Then find a formula for the nTh term of the sequence 2/5,3/6,4/7,5/8

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).
