Webm + Bn and A + B(n-1) are both equivalent explicit formulas for arithmetic sequences. A + B(n-1) is the standard form because it gives us two useful pieces of information without needing to manipulate the formula (the starting term A, and the common difference B). An explicit formula isn't another name for an iterative formula. WebFind the 9th Term 1 , 3 , 9 , 27 , 81 , 243 , 729 This is a geometric sequence since there is a common ratio between each term .
