In this problem, we have to find the partial sum of this series, that is the third partial sum, fourth partial sum, and then fifth parcel sum.
00:09
The series is here, this is sigma, from i equals to 1 to this is infinity, and then 2 multiplied with 1 divided with 3 power i.
00:21
So now for first part that is here, we have to put from i is equal to 1 to 3.
00:28
So this would be from i is equal to 1 to 3.
00:31
So this is 2 1 divided with 3 power i.
00:35
So first time would be here 2 1 divide with 3 power 1.
00:38
So simply 1 and 2 1 divide with 3 power 2 and then 2 1 divide with 3 power 3.
00:48
Simply we can here this is a constant so we can put it out...
