If you've read the text of this problem, that you know that this equation deals with the price of stocks.
00:04
Now, you can see that this could be modeled as a geometric sequence.
00:08
That is, we have our first term, a1, is equal to p.
00:12
And then we also have that our common ratio of r will be equal to, well, consider dividing the second term by the first.
00:22
And you will notice that the p's divide out, leaving us with just 1 plus i over 1 plus r.
00:27
So we have a first term in a common ratio.
00:31
Now, let's figure out some things.
00:33
Well, this is an infinite series.
00:35
So our n is just infinity.
00:37
That is, we go on forever, and we're going to be using, therefore, the infinite series formula.
00:42
Now, we're also given some values for i, r, and p.
00:45
We're told that our interest rate, i, should be 3%...
