Hello, so here we told our first term in our sequence, a sub 1 is equal to 4.
00:05
And then for any kth term, that a subk plus 1 is equal to, well, k plus 1 over 2 and then times a sub k.
00:11
So we're told our first term, a sub 1 is 4.
00:14
And then the next term, a sub 2, well, that's going to be equal to 1 times 4.
00:20
We're here, k is equal to 1.
00:22
So we get a sub 2 is going to be equal to just, well, 1 times 4.
00:28
So a sub 2 is also equal to 4, and then a sub 3, well, that's going to be equal to 3 over 2 times 4...
