We're being asked to find the first five terms for the given recursively defined sequence.
00:05
Well, remember, our first term is a sub 1, which they tell us is equal to 2.
00:10
Now, to find the second term, a sub 2, we substitute 2 in place of n in our formula.
00:15
So when we do that, we would have negative a sub 1, but remember, a sub 1 is equal to 2.
00:20
So our second term is just negative 2.
00:23
Now, to find the third term, we substitute 3 in place of n.
00:27
So we're going to have negative a.
00:28
Sub 2.
00:28
But remember, a .2 is negative 2.
00:32
So minus negative 2 would be equal to positive 2...
