In a certain code language, 'FLOWER' is coded as 'RFOELW', then 'ANIMAL' will be written as:

Let's analyze the positions of letters in the word 'FLOWER' and its code 'RFOELW'.
Number the positions of the letters in 'FLOWER' from $1$ to $6$:
1: F, 2: L, 3: O, 4: W, 5: E, 6: R

In the coded word 'RFOELW', the positions of these original letters are rearranged as follows:

* 1st letter: R (originally 6th)
* 2nd letter: F (originally 1st)
* 3rd letter: O (originally 3rd)
* 4th letter: E (originally 5th)
* 5th letter: L (originally 2nd)
* 6th letter: W (originally 4th)

So, the pattern of original indices is: $6,1,3,5,2,4$

Now, apply this exact pattern to the word 'ANIMAL':
Number the letters from $1$ to $6$:
1: A, 2: N, 3: I, 4: M, 5: A, 6: L

Rearranging according to the index order $6,1,3,5,2,4$:

* 6th letter $\to$ L
* 1st letter $\to$ A
* 3rd letter $\to$ I
* 5th letter $\to$ A
* 2nd letter $\to$ N
* 4th letter $\to$ M

Combining them gives: LAIANM
