Hi, i really cant seem to figure this question out.
I have the sum of the 5 first numbers of the sequence = 220 and then i have the sum of the whole infinite geometric sequence = 194.4
The two question i have is first
1. How do i show this information as an equation system.
5 first numbers of the sequence = 220
sum of the whole infinite geometric sequence = 194.4
2. How do i find a1 with this as my information (5 first numbers of the sequence = 220, sum of the whole infinite geometric sequence = 194.4)
3. How do i find ratio with this information (5 first numbers of the sequence = 220, sum of the whole infinite geometric sequence = 194.4)
