We're being asked to find the first five terms for the given recursively defined sequence.
00:05
Well, they already tell us that a sub 1 is equal to 1.
00:07
Therefore, the first term in this sequence is 1.
00:11
Now, to find the second term in the sequence, we just need to substitute 2 in place of n.
00:15
So we'll have 2 minus a sub, while 2 minus 1 is 1.
00:19
So we have 2 minus a sub 1.
00:21
But we already know that a sub 1 is equal to 1.
00:24
So we're left with 2 minus 1, which is equal to 1.
00:27
So the second term in the sequence is also 1.
00:30
Now, to find the third term in this sequence, we substitute 3 in place of n.
00:34
So we'll have 3 minus a sub, 3 minus 1, which is 2...
