Hello.
00:01
Okay, so here we're given that our initial value here, u0, u sub 0, is equal to 3.
00:08
And then we're told that, well, you, so this is, if we have u sub t, then u sub t plus 1, right, it's going to be equal to 2 times u sub t plus 1, but then this is going to be mod, mod 5.
00:25
So if u sub 0 is equal to 3, then u sub 1 is just equal to, well, that's going to be u sub t plus 1.
00:34
So u sub 0 plus 1, or u sub 1 is going to be equal to 2 times u sub 0.
00:39
So it's going to be equal to 2 times 3 plus 1.
00:45
So that's going to be equal to times 3 is 6 plus 1.
00:50
That's equal to 7, but 7 mod 5.
00:53
So this is equal to 7 mod 5, but 7 mod 5 is equal to 2, right? because that is the remainder when we divide by 5.
01:02
So the first blank here is going to be 2...
