This is what we call a Fibonacci sequence:

Notice that after the 1,1:

4th term =3 ==> 2+1

5th term =5 ==>3+2


6th term =8==> 5+3

7th term = 13==> 8+5

8th term =...........13+8 =21

9th term = ...........21+13 =34

10t=h term =........34+21 = 55

In short each number equal the sum of the 2 preceding number
