Answer 144 which is F(12) Reason 55 and 89 are the 10th and 11th Fibonacci numbers, If we add these we have 144 which is the 12 Fibonacci number and is a perfect square. I am using F(0) as the 0 Fibonacci number and F(1) as the first.
The 365th Fibonacci number is 8531073606282249384383143963212896619394786170594625964346924608389878465365.
The 100th Fibonacci number is 354,224,848,179,261,915,075.
How to answer with formula
The 16th number of the Fibonacci sequence is 987.
The twelfth Fibonacci number is 144.
34, 55, 89, 144 is a portion of the Fibonacci sequence. The next number is 89 + 144 which is 233.

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.
144
Fibonacci sequence adds the previous two numbers to get the next number. 1,1,2,3,5,8,13,21,34,55,89,144,233,377,610,987,1597
He worked on the Fibonacci number. It goes like this: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, . . .
A Fibonacci number, is a number in the famous Fibonacci series, which is every new number after the two seed numbers (0, 1) are the sum of the previous two numbers:0, 1, (0+1), (0+1+1), (0+1+1+1), (0+1+1+1+1+1), ...0, 1, 1, 2, 3, 5, ...Recursively, it can be written as:Fn = Fn-1 + Fn-2In order to use therecursiveformula, you would have to know the previous two terms. Without getting into too much detail, a simple formula you can use to see if a number is a fibonacci number, is to verify if (5N2 + 4) or (5N2 - 4) are perfect squares, where N is the number you are checking.(5 (707)2 + 4 ) = 2,499,249(5 (707)2- 4 ) = 2,499,241√2,499,249 ~= 1580.9 (not an integer)√2,499,241 ~= 1580.9 (also not an integer)Therefore 707 is not a Fibonacci number.To demonstrate how this works with a Fibonacci number, let's try 144.(5 (144)2+ 4 ) = 103,684(5 (144)2- 4 ) = 103,676√103,684 = 322 (is an integer => a perfect square)√103,676 ~= 321.988 (not an integer)Only one of the tests has to be true, and therefore 144 is a Fibonacci number.
the first seven Fibonacci numbers are 1,1,2,3,5,8,13. 13 is a Fibonacci number.
The 22nd Fibonacci number is 17,711
The 365th Fibonacci number is 8531073606282249384383143963212896619394786170594625964346924608389878465365.
The 100th Fibonacci number is 354,224,848,179,261,915,075.
