There is no Fn on the Periodic Table of elements. However, there is Fm, Fermium, number 100.
The FN key stands for function and then your f1 f2 ...... keys Also, in mathematics it stands for Fibonacci number, Fn. But you probably mean on the computer keyboard.
Fn = Fn-1 + Fn-2
Fn = Fn-1 + Fn-2 And F0 = F1 = 1
fn a5
Code FN shown on display and function on equipment not working .
You will have to call FN to find out.
No sn data for FN weapons in the public domain.
The first number, f1 = 1 The second number, f2 = 1 After that the sequence is defined recursively: fn = fn-1 + fn-2 for n=3, 4, 5, ...
F(n) = 10n + 1
The output is 1 more than 10 times the input.
Foot Note
The two number before a number are added to get the next number. So if the first numbers are 0,1,1,2,3,5, and 8 for example. You add 0+1=1 which is the third number. 1+1=2 which is the 4th number in the sequence etc. Of course, you can do this forever so the sequence is infinite. In symbols we write the sum as Fn =Fn-1 +Fn-2 The n refers to the nth number in the sequence. For example if n=4, than Fn =2
