Answer: 9 is the next number of this series. Similarly, apply thus rule. 9×2=18 and 18+9=27. Next is 27.
Step-by-step explanation:
This is part of the Fibonacci sequence. The next number is 21. Look at how much each number increases and the number before it.
1+1=2 (the number after 1 and 1)
1+2=3 (the number after 1 and 2)
2+3=5 (the number after 2 and 3)
So to solve we add 13+8=21
