We want to determine whether it is true that if a sequence has all these terms being positive numbers, must it converge if it is bounded for a book.

And we want to give a reason as to why.
00:15
Well, i'm going to say that this is false.
00:20
And the reason i'm going to say that is we can just have an alternating sequence of 1 and 2.
00:31
So if we had the sequence 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, so on and so forth.
00:44
Or in other words, we can write a .n is equal to 1 when n is odd, and 2 when n is even...
