What is the next number in this pattern

21

Step-by-step explanation:

8+13=21

as 3+5= 8 ; 5+8=13

21

Step-by-step explanation:

You add the number prior to the number on the pattern. So you add 3 to 5 and get 8. You add 8 to 5 to get 13 and then you add 13 to 8 to get 21. It also shows that 21 is correct since 21 + 13 is equal to 34. Which 34 is the next number in the sequence after the blank space.

This also follows the pattern in 55 and 89.
