Intro to geometric sequencesSal introduces geometric sequences and their main features, the initial term and the common ratio.

Using explicit formulas of geometric sequencesSal finds the 5th term in the geometric sequence whose explicit formula is 3(-¼)^(i-1).

Using recursive formulas of geometric sequencesSal finds the 4th term in the sequence whose recursive formula is a(1)=-⅛, a(i)=2a(i-1).
