Answer:

  • Neither

Explanation:

Given sequence:

  • 3, 5, 9, 17, ...

We can write the terms as:

  • 3 = 2^1 + 1
  • 5 = 2^2 + 1
  • 9 = 2^3 + 1
  • 17 = 2^4 + 1
  • ...
  • aₙ = 2^n + 1

As we see the sequence doesn't meet AP or GP criteria, there is no common difference or common factor between the terms
