What is the seventh term of a sequence whose first term is 1 and whose common ratio is 3?

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.

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
