We're being asked to find the first five terms in the sequence that's given by the given recursive formula.
00:06
Well, the first term they give to us, a sub 1, a sub 1 is equal to 2.
00:11
Well, let's look at our recursively defined formula.
00:15
Well, we're told that a sub n is equal to 3 plus a sub n minus 1.
00:19
Well, remember, a sub n minus 1 means the previous term.
00:25
So now when we go to find a sub 2, we're going to have 3 plus, the previous term, which in this case is 2.
00:34
Well, 3 plus 2 is equal to 5.
00:36
So the second term in the sequence is 5...
