21. Your example is in the Fibonacci series.
fibonacci sequence :)
It is called a Fibonacci number sequence! 1,1,2,3,5,8,13,21...
Fibonacci Sequence.
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.).
Fibonacci Sequence
It is the next odd number.
The next number in the sequence is 20. You are alternately multiplying the previous number by two and then subtracting two.
The sequence 0112358 represents the Fibonacci sequence, where each number is the sum of the two preceding ones. The next number in this sequence is 13, as it is the sum of the last two numbers, 5 and 8. Thus, the next number is 13.

51. Just add two to an odd number to work out the next ;)
