Okay, so we want to find our first five terms of our following sequence.
00:04
So we have a1.
00:06
This is six times one over three.
00:08
We replace our n with our one, so that's one minus one.
00:11
So this is just equal to a six.
00:13
And then we want a2, that's six times one over three.
00:17
And then we have two minus one, so that's a one.
00:19
That's six over three.
00:21
And that's equal to the two.
00:23
And now we want a3, that's six times one over three to the power of three minus one.
00:30
So that's 2.
00:31
So that's equal to 6 over 3 squared, which is 9.
00:34
Well, 6 is 3 times 2, and 9 is 3 times 3...
