Step-by-step Solution:

\[ \begin{array}{|c|c|c|c|c|c|c|c|c|c|c|c|c|} \hline \textbf{Alphabets} & A & B & C & D & E & F & G & H & I & J & K & L & M \\ \hline \textbf{Positional value} & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 & 11 & 12 & 13 \\ \hline \textbf{Positional value (Reverse)} & 26 & 25 & 24 & 23 & 22 & 21 & 20 & 19 & 18 & 17 & 16 & 15 & 14 \\ \hline \textbf{Alphabets (Reverse)} & Z & Y & X & W & V & U & T & S & R & Q & P & O & N \\ \hline \end{array} \] 1. First Row (First Letters of the Series)
E → G → I → K → M
Rule: Each letter increases by +2 in the alphabet.
2. Second Row (Second Letters of the Series)
L → L → L → L → L
Rule: Constant 'L' (No change).
3. Third Row (Third Letters of the Series)
F → H → J → L → N Rule: Each letter increases by +2 in the alphabet.
4. Fourth Row (Fourth Letters of the Series)
A → A → A → A → A
Rule: Constant 'A' (No change).
So, Result is KLLA.
