No, 38 is not a Fibonacci number. The Fibonacci numbers closest to 38 are 34 and 55. 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, etc.
Fibonacci sequence Fibonacci sequence
37 is not in the Fibonacci number series, but is the sum of two Fibonacci numbers, 34 and 3. Fibonacci numbers are with 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, etc.
The missing number is 21. This follows the pattern of the Fibonacci sequence where each number is the sum of the two preceding numbers.
the first seven Fibonacci numbers are 1,1,2,3,5,8,13. 13 is a Fibonacci number.
Assume the question refers to the standard Fibonacci sequence where the first two numbers are 0 and 1.The sequence progresses :- 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 - which is the number required.
The 365th Fibonacci number is 8531073606282249384383143963212896619394786170594625964346924608389878465365.
