Okay, so we want to find the summation of the following.
00:03
So notice here that our starting value is at zero.
00:07
So we need to rewrite this in terms of a starting value of 1.
00:11
So we can set another variable.
00:14
Let's got it k.
00:15
Let's set that equal to our i value plus 1.
00:21
Okay.
00:23
So then we get 0 plus 1, which gives us the starting value of 1.
00:28
Okay, so if i set this equal to k, then let's solve for i.
00:33
I is equal to k minus 1.
00:37
And now let's rewrite this summation.
00:39
So i have a sum from our k is now equal to 1.
00:51
And then we have, we need to also add a 1 to our n.
00:55
So we have n plus 1.
00:58
Our i is now k minus 1...
