Can you tell me the solution to these two patterns?

Question

2, 2/3, 4/3, 5/4

1, 8, 27, 64, 125

Thank you!

Answer 1

second one are cubes

an = n^3

the first one, I think the second number should be 3/2, then you have

an =(n+1) / n

Answer 2

The 2nd sequence is simply successive cubes of integers starting with 1:

1^3, 2^3, 3^3, 4^3, 5^3, 6^3 etc.

Not sure about the first question.
