Type the missing number in this sequence:

3,
, 27, 81, 243

Answer 1

The missing number would be 9.

Explanation:

I found out that the rule is 3 multiplied.

3 times 3 = 9

9 times 3 = 27

27 times 3 = 81

81 times 3 = 243

Answer 2

27 * 3 = 81

81 * 3 = 243

Each term is 3x the number before it. Therefore:

3 * 3 = 9

The missing number is 9.
