Answer:
729
Step-by-step explanation:
The formula for these types of problems is a(n)= (a)(r^n-1) where a is the value of the first term, n is the term you wish to find, and r is the common ratio. Once you plug in the numbers, you will get a(n)= (1)(3^7-1), or a(n)= (1)(3^6)
After you solve this, you will get 729.
