To prove that, the sequence xn is equal to 1 over 2, xn -1 plus x of n -2, where x0 is equal to 0 and xn is equal to 1 for all greater than equal to 2 is convergent.
00:27
So, now from here, find x2, that is 1 over 2, that is x1 plus x0.
00:35
Now, x3, that is 1 over 2, x2 plus x1, x4, that is 1 over 2, x3 plus x2, dot dot dot.
00:51
Now, xn is equal to 1 over 2, xn -1 plus xn -2.
00:58
Now, find xn plus 1, that is 1 over 2, that is xn plus x of n -1.
01:08
Now, add xn plus 2 is equal to 1 over 2, xn plus 1 plus xn.
01:16
Now, add on adding left -hand side and right -hand side, we will get, after adding, we will get x2 plus x3, x4, dot dot dot, xn, xn plus 1, xn plus 2...
