So, the next two numbers are 55 and 89
So,
1+1=2
1+2=3
2+3=5
Starting at the 1,1 add them together to get the next number which is 2. Then 1,2 add 1+2 to get the next number which is 3. Next, 2,3 add 2+3 to get the next number which is 5
I hope you understand that. I tried to explain it at the best of my ability
