Review geometric sequences before you dive into geometric series.
Sal introduces geometric sequences and their main features, the initial term and the common ratio.
Sal introduces geometric sequences and gives a few examples. Notation used in this video is relatively advanced.
Given the first few terms in a geometric sequence, find the next term in the sequence.
Given the formula of a geometric sequence, either in explicit form or in recursive form, find a specific term in the sequence.
Sal finds an explicit formula of a geometric sequence given the first few terms of the sequences. Then he explores equivalent forms the explicit formula and finds the corresponding recursive formula.
Solve problems such as: The first four terms in a geometric sequence are 1/3, 1, 3, and 9. Find an explicit formula for the sequence.
Sal solves the following problem: The explicit formula of a geometric sequence is g(x)=9*8^(x-1). Find the recursive formula of the sequence.
Find the recursive formula of a geometric sequence given the first few terms or given an explicit formula.
Given a verbal description of a real-world relationship, determine the sequence that models that relationship.
