Answer 3

Just keep adding until you get to the 10th term.

You are given the first two terms and the rule for getting the next term.

So, it starts like this:

1, 1, 2, 3, 5, ...

There are the first five terms. Add 5 to 3 to get the sixth term and keep going to reach the tenth term.

1,1,2,3,5,3,11,14,17,20
