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

<span>6 times 4x = 24x </span>
<span>6 times 1 = 6 </span>
