Inner function( fun(x-1) )is called first which returns 2 . value 2 becomes argument for another inner function (fun(2)) and this is how it goes on ..

You should start with the innermost function fun(x-1) and put for x 5. That mesns fun(5-1) = fun(4). So from definition of the function: x= 4 - (4 - 2) = 4 - 2 = 2 So this return 2. When you put this 2 into next function fun you get: fun(2) = 2 - (2 - 2) = 2 and so on, and so on. For this reason the result is 2.
