If the last number is 1/3 (it should be), the next number is 5 and 1/3
The answer is 34. The full sequence is called the Fibonachi series. Your sequence is 3 5 8 13 21 3 + 5= 8 8 + 13 = 21 Therefore: 13 + 21 = 34
The next number in the sequence 3-15-6-30-21 is -207.

The pattern in the sequence 0, 3, 9, 21 involves adding consecutive odd numbers. Starting with 0, then adding 1+2, 3+6, and 9+12 gives you the next number in the sequence. Therefore, the next number would be 21 + 15 = 36.
8 and then 1.6

This is a Fibonacci sequence. Each number in the sequence is the sum of the previous two numbers:3+5=85+8=138+13=2113+21=34
The answer is 21.Your numerical series is the beginning of a mathematical sequence called Fibonacci Numbers.The first number of the sequence is 0, the second number is 1, and each subsequent number is equal to the sum of the previous two numbers of the sequence itself (i.e. 0, 1, 1, 2, 3, 5, 8, 13, 21, etc.).
The sequence is taking half of the number and adding it to that number, 3/2 = 1.5, 3 + 1.5 = 4.5, the next number in the sequence is 15.1875
