How to write the sum in sigma notation given a geometric sequence
š Learn how to write the sum from a geometric series. A series is the sum of the terms of a sequence. A geometric series is the sum of the terms of a geometric sequence. The formula for the sum of n terms of a geometric sequence is given by Sn = a[(r^n - 1)/(r - 1)], where a is the first term, n is the term number and r is the common ratio. To write the sum we will either be given the series as a sum or written in sigma notation. Either way, we will need to determine the rule of the sum by identifying the common ratio and first term. šSUBSCRIBE to my channel here: https://www.youtube.com/user/mrbrianm... ā¤ļøSupport my channel by becoming a member: Ā Ā Ā /Ā @brianmcloganĀ Ā šāāļøHave questions?
