Worksheet 3 6 Arithmetic and Geometric Progressions
maths.mq.edu.auA geometric series is a geometric progression with plus signs between the terms instead of commas. So an example of a geometric series is 1+ 1 10 + 1 100 + 1 1000 + We can take the sum of the rst n terms of a geometric series and this is denoted by Sn: Sn = a(1 rn) 1 r Example 5 : Given the rst two terms of a geometric progression as 2 and 4, what
The sum of an infinite series
www.mathcentre.ac.ukseries mc-TY-convergence-2009-1 In this unit we see how finite and infinite series are obtained from finite and infinite sequences. We explain how the partial sums of an infinite series form a new sequence, and that the limit of this new sequence (if it exists) defines the sum of the series. We also consider two specific
