A Correct answer
Explanation

The series is powers of 3: 3^1, 3^2, 3^3, 3^4, 3^5, 3^6. Missing terms are 3^4 = 81 and 3^6 = 729.

AI explanation

The series follows a geometric progression where each term is multiplied by 3 to get the next term. Multiplying 3 by 3 gives 9, 9 by 3 gives 27, and 27 by 3 gives the first missing term of 81. Continuing this multiplication, 243 times 3 results in the second missing term of 729.
