What is the explicit formula for the sequence 2,6,18,54

X*3

2 times 3 is 6

6 times 3 is 18

Etc

Step-by-step explanation:

1. you could just divide 54 by 8 or 6 by 2 to get what your multipllying by.

2. when you divide 54 by 18 you get 3, same as 6 divided by 3 = 2

3. so you check it out and think 2*3=6*3=18*3=54
